Do-it-yourself gas burner for linokrom. Roofing burner - necessary equipment for the installation of built-up roofing

Literally in two decades, construction technologies have been updated, new building materials and tools have appeared. For example, the old faithful roofing material has given way to new roofing welded materials, which are better in all respects. Nobody will argue with this. And accordingly, a bucket with hot bitumen and a brush for coating went into oblivion, instead of which builders use today a gas burner for roofing.

What is a gas burner

This is a hand tool connected to a gas cylinder. It consists of:

• A nozzle inside which a jet with a through hole of small diameter is installed. Through it, gas in the form of a flame is supplied to the place of surfacing or drying.
• Cup. This is a device inside which a combustible gas is mixed with air (oxygen). There are many holes in the glass through which air is sucked into the flame zone. In addition, this device protects the flame of fire from the effects of wind.
• A valve that opens the gas supply and regulates its pressure, and, accordingly, the length of the torch.
• The main pipe that separates the torch from the handle that the welder is holding on to.
• Handle made of plastic or wood.

Of course, to operate a gas burner, you need a hose connected to the cylinder and a reducer that lowers the gas pressure in the line. The gas pressure at the outlet of the burner is 0.1-0.15 MPa. The propane gas burner for roofing weighs a little, in the range of 1.0-1.5 kg. So it is convenient and easy to work with her.

How to make a burner with your own hands

In principle, the design of a propane gas burner is simple. The main thing is to collect the nozzle and glass. The remaining elements and parts are ready-made components and parts that are sold at any hardware store. Therefore, it will not be difficult to make it with your own hands.

So, what is required to assemble the burner with your own hands.

Gas burner assembly

First of all, you need to cut an internal thread at one end of the copper tube using a tap of the appropriate diameter. Copper is not a very hard metal, so it will not be difficult to carry out this operation with your own hands. It will also be easy to screw the jet.

With a glass, everything is more complicated. To do this, you will have to cut one side of the pipe into several longitudinal petals (6-8 pieces), and then bend them to the center. You get a cone, while you don’t need to bring the petals to the end, you need to leave room for the main tube, on which the glass is put on. After that, the petals are pressed against the tube, where they are sealed. Slots remain between the petals, which will perform the functions of supplying air inside the nozzle. The length of the petals is approximately one third of the entire length of the glass.

Important! The jet should be located at a distance equal to the length of the petals. That is, a flame of propane and oxygen should form at the level of the slots.

A gas burner for roofing, or rather, its front part in the form of a nozzle is ready. It remains to assemble the back. To do this, you will need two M25 drives, made from a pipe with a diameter of 25 mm with threaded threads. In a one-sided drive, in a place where a thread is not cut, a cone is formed into which the back of the main tube is inserted. This can be done by heating the squeegee with an oxygen cutter, and tapping it from all sides.

A gas control valve is screwed into it. The second round, it is double-sided, is screwed into the valve from the other side. Be sure to wrap on the sealing material. For example, on a fum tape. An adapter from a threaded connection to a hose connection is screwed onto the rear end of the second spur. It makes no sense to make it with your own hands, because it is sold in any hardware store and is very cheap.

Now it remains to make a handle and install it on the prepared device. Handle options are plentiful. The main thing here is to comfortably hold the entire home-made device. For example, it can be cut from a wooden board 5 mm thick, you can buy an ax handle and fit it to the size and shape. It is better to attach the handle to the sleds, because in the whole structure this is the most durable section. Optimally, this is the rear sway, because the control valve should be located slightly forward for ease of use.

You can attach a piece of wood to a metal tube in different ways.

• Make a recess across the entire width to fit the diameter of the pipe, put the pipe into it and secure it with two clamps from a metal tape.
• Install the crank on the side of the handle and also secure with clamps.

So, a do-it-yourself gas burner for roofing is made, you can connect it to a gas cylinder and test it. To do this, the hose is connected to the cylinder through a reducer, where it is fixed with a clamp. Its second end is threaded into the adapter, where it is also fixed with a clamp.

The cylinder opens, the propane supply through the gas reducer opens. And the last to open is the regulating valve on the injector. Gas should go through the jet with a characteristic sound. It is necessary to wait until the air inside the device is completely out. Then the gas stream is ignited. The valve near the handle regulates the torch in length and power.

Attention! Homemade gas burner for roofing - a device of increased danger. Therefore, all operations performed must be approached with special care. This is especially true for the connections of all elements to each other. Full tightness must be observed.

Fire safety measures

Regardless of whether a factory-made gas burner or a home-made one is used, fire safety requirements must be strictly observed.

• Keep a fire extinguisher on the roof when doing roofing work.
• All work is carried out only during daylight hours.
• When laying a soft roof with a gas burner, only one propane cylinder can be brought onto the roof.

For a soft roof, the optimal hydro- and heat-insulating materials are those that are welded using a roofing burner. This is labor-intensive and complex work, which, moreover, is performed at height. The result of high-quality installation will be a long service life of the roof. Therefore, only high-quality equipment is selected for work. In the article, we will consider the existing types and advantages of various roofing burners.

What is a roof burner

This is a special equipment for heating the built-up roof. In addition, with the help of a burner, the surface is dried, workpieces are heated for construction work, building paint is fired and used in all work where it is required to heat elements or surfaces.

The gas burner for the roof consists of:

• a metal cup made of heat-resistant material;
• gas supply hose;
• nozzles for ignition of a torch with protection against wind.

The roof burner is a mobile design with comfortable handles for carrying it. It has a small weight, up to 1.5 kg, and is equipped with a convenient handle made of wood or plastic up to 1 m long.

Propane is the most commonly used gas. It enters the body through a gas pipeline. Regulate its supply and the length of the flame using a special valve on the burner. To save gas consumption, roof burners are equipped with a gearbox that controls the fuel consumption.

In all designs of gas burners, an atmospheric air suction system is provided. This is a mandatory feature, but there are additional ones that make the work more comfortable. First of all, the ability to regulate operating modes. For example, when work is interrupted, standby mode is activated and fuel is saved. Any gas burner is ignited with regular matches or a lighter.

Less popular, but also used for roofing, are diesel-fuelled burners.

Application of gas burners

They are used in most branches of construction and industry.

The design of gas burners depends on the fuel on which they operate and on the area of ​​application. But in general they are identical. The burner, consisting of a body, a lever for adjusting the flame of a valve for supplying fuel, is connected to a gas cylinder through a reducer. Some manufacturers supplement the designs of gas burners with additional flame wind protection and piezo ignition.

Types of gas burners

For laying roofs made of bituminous materials, hand burners are used. Most often, these are propane burners for the roof of a lever structure. They are easy to use - the length of the flame is easily adjusted by simply pressing the lever mechanism, switching to an economical mode of gas consumption.

During operation, the gas burner consumes a mixture of propane with air or with the addition of technical oxygen. Gas-air burners are the safest for operation. They provide sufficient temperature for roofing, heating metal parts, annealing paint and soldering cables.

Valve-type gas burners are easy to use, light in weight and do not cause difficulties in repair. By creating a high flame with high power, they make it possible to work even in windy weather.

There are also acetylene torches that run on a mixture of acetylene and oxygen. Most often they are used for welding. They are designed in such a way that oxygen, in injection acetylene burners, is needed not only to maintain combustion, but also to supply acetylene.

In addition, burners differ in functionality and have different abbreviations:

GV 500

Are applied at roofing works. It is capable of creating a heating temperature of up to three hundred degrees, which is quite enough for fusing all bituminous materials;

GV 850

More advanced model. It has a valve for fine adjustment of the technical gas supply from the cylinder. And thanks to the lever, the length of the flame is easily adjusted during work. Its power is enough to melt metal-plastic pipes and refractory cables.

GV 3

Runs on propane. It is used for heating and welding of metal and hand soldering. The size of the glass diameter is 5 cm.

GGS1-1.7

The most versatile and most popular burner. Heats the surface up to four hundred degrees. It is used when laying soft roofing materials, road and waterproofing works. Power is 115 kW with fuel consumption of 9kg/h.

GGS1-1.0

It is irreplaceable for work in limited space and on a roof with a big angle of inclination. It is a good replacement for a conventional blowtorch. With small dimensions (length 50cm) it has great power, is safe, economical and convenient to use. Its power is 40 kW, and the gas consumption is 3 kg/h.

GGS1-0.5

It is used for small roofing repair, soldering, welding of cables. Due to economical fuel consumption, it can work with a five-liter gas cylinder. The power is 10 kW, the consumption is 0.7 kg/h.

GGS2-1.5

Equipped with two parallel sockets, thanks to which it has a high performance. Power 179 kW with fuel consumption 14kg/h.

GGS4-1.0

Or a spreader. It has 4 sockets, which provides simultaneous heating with a width of 1 meter and allows you to work non-stop. There are special hooks for the roofing material along the cuts; with their help, one person can perform all the work on laying it. Power 120 kW, consumption - 12 kg/h.

Gas burners are used in all types of construction and repair work and can heat surfaces up to four hundred degrees. In particular: gas-air injection burner GG-2, gas burner GVK 1, liquid fuel burner GRG-1, propane burner GSP-3, propane burner GVK-1-R, propane burner GSP-4 and others.

The price of gas burners for roofing varies greatly and depends on many factors: performance, additional functions, the ability to work with a particular fuel, as well as the manufacturer. It is worth noting that they are inexpensive and available to most consumers.

What you need to know when working with a gas burner for a soft roof?

Consider this on the example of roofing work when laying roofing material:

• first, the entire surface is cleaned - not only large debris is removed, but also fine dust;
• for marking, sheets of roofing material are laid out on the roof with an overlap of up to 10 cm, after which it is twisted, and the edges of all sheets are fixed with a gas burner at the base of the roof;

• during operation, a roll of roofing material is rolled out gradually, melting and pressing tightly to the roof surface. All wrinkles and bubbles under the material should be removed immediately. When working on flat roofs, this is done using a hand roller;
• the final stage of work with a gas burner will be the heating of all seams of the roofing material. When heated, it melts, sticking tightly to the bottom sheet. Additionally, the seams are reinforced with a hand roller.

When a high-quality gas burner with adjustable fuel supply is used for work, up to 600 m of roofing material can be laid non-stop.

Important! It is allowed to use a gas burner for a soft roof at a temperature not lower than 15 degrees. If work is required at a lower temperature, an oil burner will be required.

Safety precautions when working with a roofing gas burner

• Roofing work is required in special clothing and shoes with non-slip soles;
• use the safety system;
• Before use, the gas burner is carefully inspected. It is necessary to make sure that all structural elements are in good condition;
• during the operation of the burner, there must not be a second gas cylinder on the roof. Also periodically it is necessary to check the tightness of the hose connection with the reducer and the cylinder;
• when igniting the burner, in no case should you be in front of the nozzle;
• adjust the height of the flame so that it does not touch the cylinder, hose or people;
• when heating the welded roofing material, it must not be allowed to ignite;
• only the lower part of the sheet should be melted, without softening the entire thickness of the material;
• when igniting a propane burner, first open the valve half a turn and leave it to purge for a few seconds. And only then can the mixture be ignited and the height of the flame can be adjusted;
• with a working gas burner, it is forbidden to leave the working area or climb the scaffolding;
• to extinguish the burner, the gas supply is first blocked, and then the lock lever is lowered;
• if the burner overheats or a backlash occurs, work is immediately stopped, the gas is shut off, and the burner is placed in a container of cold water to cool.

Buy a ready-made burner or make your own?

It should be said right away that it will be much easier and safer to buy a ready-made burner than to make it yourself. But if you have confidence in your abilities and love to do everything with your own hands, then you can try.

A gas burner is a complex device and in order to make it you will need certain skills and thorough adherence to many rules. But still, part of the work is best left to professionals. First of all, this concerns the supply system and gas storage tanks.

For the manufacture of a torch, a metal rod and a divider are used. They are attached to the handle made of heat-resistant wood.

The gas supply hose is borrowed from the gas welding system or independently machined from brass.

Despite the fact that outwardly a do-it-yourself roofing burner will differ significantly from store counterparts, it will cope with its main functions.

But when working with it, you will have to pay special attention to the slightest gas leaks or other malfunctions. And even with a minor problem, work should be stopped immediately.

Roof diesel burner

These roofing burners operate on liquid fuel. They are especially relevant for operation at a large temperature minus, in which case they are equipped with built-in fuel heating. They are fully automated and are able to work with fuel of various qualities. The diesel roof burners are equipped with a high-pressure blower system that ensures stable and safe ignition and reduces soot formation.

Liquid fuel burners are structurally different from gas counterparts. In diesel fuel, the fuel enters the chamber under high pressure, which causes the liquid to be atomized. And the smallest particles already sprayed are ignited at the outlet of the nozzle, creating a flame. In this connection, the burner is connected to the compressor and the fuel tank using oil and petrol resistant hoses.

The oil fired roof burner is designed to operate under the following conditions:

• at ambient temperature from - 25 to + 40 degrees;
• at atmospheric pressure - 101 kPa;
• if necessary, flame temperatures up to 600-800 degrees.

In this case, the approximate consumption of diesel fuel is 10 l / 100 m2 of area.

How to work with a diesel roof burner:

• check the serviceability of all structural elements;
• turn on the compressor to supply air to the nozzle. Then, having opened the fuel supply valve, bring a special igniting tourniquet to the nozzle. After igniting the diesel fuel supply tap, adjust the flame level.

For repair and other roofing work, which involves melting mastics and laying roofing materials, you will need a special gas burner. The device is mainly used for the following tasks:

— heating and drying of roofing materials;

— cutting and soldering of metal;

— firing a layer of old paint.

Approximate structure of a gas burner

The gas burner has a fairly simple design. It is a glass made of metal and equipped with a nozzle and a handle, which is fixed on the body. . For the manufacture of the handle, heat-resistant plastic or wood can be used. The gas enters the housing by passing through the gas pipeline. In most cases, propane under pressure is used to operate the burner.

The burner cup must be shaped to protect the flame from wind blowing.

The burner body has a valve that allows you to adjust the length of the flame and the intensity of the supplied gas. It is good if the burner has a gearbox that allows you to save gas.

Components of a roof burner

In the process of assembling the device, mechanical processing is practically not used. The burner is assembled from ready-made spare parts. For its manufacture we need:

1. Steel valve, which can be taken from a cylinder designed to store liquefied gas.
2. A cap that is used to transport gas cylinders.
3. Jet from a blowtorch with a nozzle diameter of 0.8 mm.
4. A piece of pipe one meter long with an internal diameter of 10 mm. and steel thickness 2 mm.
5. Wooden handle.

As a handle, you can use the handle from a burned-out soldering iron.

Step-by-step burner manufacturing process

The process of manufacturing a gas burner begins with the fact that we insert the supply tube, for which we will use a steel pipe, into the handle and fix it with glue. The divider and the body must be machined from a brass bar, the diameter of which should be 20 mm. In the finished case, two radial holes are drilled (each with a diameter of 5 mm.) And four holes in the divider rod (each with a diameter of 1 mm.).

When assembling, it is necessary to press the divider into the body with a slight interference fit. At the same time, the flange is installed inside the housing with a clearance, that is, the inner diameter of the manufactured housing must be 0.6 mm larger. bored diameter. The resulting gap is responsible for the deceleration of the gas flow, which is supplied to the drilled holes in the igniter.

To make a thin hole in our nozzle, you need to take a drill with a diameter of 2 mm. and use it to make a blind hole, which is 1.5 mm. does not reach the exit. Drill with a diameter of 0.4 mm. used for jumper. The resulting hole must be completely minted with gentle hammer blows. Then you need to sharpen the end. To do this, we take sanding paper and grind it until the desired cross section of the outlet is found, that is, until the nozzle can be put on the tip of the threaded burner tube.

At the end of the gas supply pipe, it is necessary to put on a supply hose made of fabric-rubber material. We fix the hose on the tube with a clamp. We set the working pressure, after which we supply gas. Wait until all the air is forced out of the hose, and only then bring the nozzle into the flame of a gas burner.

In the process of roofing, it is often necessary to use a gas burner. This equipment is used for quick drying of non-combustible surfaces, burning old paint, heating bituminous materials, etc. Various types of burners are used in construction. For example, a roofing propane burner is often used, burners that run on diesel fuel are often used. Let us consider in more detail the features of this equipment.

A roofing burner is a device that generates a flame by burning a certain type of fuel. Burners are used mainly for heating bituminous components, but can be used for other purposes. For example, for firing an old layer of paint or for quick drying of a damp surface.

Let's take a closer look at how a roofing burner works, and also get acquainted with the basic principles of working with this equipment.

Types of burners

Today it is possible to purchase burners of various types, the main difference between different models is the type of fuel used.

Gas

The most commonly used gas burner for roofing. This equipment is a system that includes two elements - a fuel tank and a torch. The elements are interconnected by a hose. The advantages of this design include:

• High level of mobility;
• No need to monitor the level of gas supply;

• Regulators that allow you to control the pressure of the flame are located directly on the torch.

Advice! In gas burners from different manufacturers, there may be slight differences in the design of the torches, as well as in the volume of gas cylinders. However, the principle of operation for all models is the same.

The gas roofing burner gained wide popularity, first of all, because of the low cost of fuel. However, as with any other gas equipment, when using burners, you will need to comply with fairly stringent safety requirements.

Propane

A propane-powered roofing burner is, in fact, a gas burner, and structurally it differs little from it. However, this type of burner is allocated to a separate group. The most important difference between propane torches is the ability to use standard gas cylinders that are used in conventional gas welding.

In addition, propane is safer than natural gas, and propane burners produce a more powerful flame at a higher temperature.

Advice! It is necessary to purchase gas, including propane, burners only in trusted trading enterprises that guarantee the quality of their products. It is very dangerous to work with homemade burners!

Diesel

The roofing diesel burner belongs to the class of liquid fuel, so the design is different. Inside the torch of such a burner, a nozzle is installed into which fuel and air are supplied. The created mixture after ignition forms a flame of a sufficiently high temperature.

Diesel burners are no less mobile and efficient than gas burners. Plus they are safer. Fuel for diesel burners is more expensive than gas, however, since it is used economically, the total costs for working with gas and diesel burners are almost equal.

However, diesel burners are used somewhat less frequently than gas burners; even diesel models are not so common on sale.

Safety regulations

When planning to work with gas burners, you should first familiarize yourself with the safety rules:

• When working with any type of burners, it is necessary to use overalls: tight trousers, shoes with non-slip soles, protective gloves. To work on the roof, it will be necessary to use other devices - a mounting belt for easy carrying of tools, navigation bridges, etc.
• Before starting work, it is necessary to carry out an external inspection of the equipment - burners, gas cylinders, hoses. If defects are found, it is necessary to refuse to carry out work until the malfunction is eliminated.

• When working with a gas burner, it is allowed to keep only one (working) gas cylinder at the workplace. Additional cylinders will need to be lifted to the job site as needed. Empty cylinders are immediately removed from the site.
• In the process of work, it is necessary to constantly ensure that the joints of the hoses with the burner and the cylinder are tight.
• When igniting the burner, make sure that the flame is directed away from people, the gas cylinder and the connecting hoses.

• When igniting the propane burner, the valve is opened half a turn. After the flame flares up, you will need to adjust its length.
• It is not allowed to leave the work area holding a lit burner. It is strictly forbidden to climb the scaffolding with a burning burner in hand.
• In order to extinguish a gas burner, you must first shut off the gas supply and only then lower the flame lock lever.
• Even with a short interruption in operation, the burner must be extinguished.

Stages of work with a roof burner

When laying welded roll materials on the roof, it is impossible to do without the use of a roofing burner. Installation work takes place in several stages:

• First you need to prepare the base well. The surface of the roof is thoroughly cleaned, and if necessary, the base is leveled by performing a screed.
• Then sheets of material are rolled out over the roof, positioning them so that they lie with an overlap of 9 cm wide.

• After making sure that the sheets of material lie correctly, the material must be rolled up again. The extreme part of the material is fixed at the edge of the roof.
• Then the heating of the lower part of the bale begins, gradually unfolding the bale and rolling it with a heavy manual roller.

• When laying the roll material, overheating should not be allowed. It is important to ensure that only the lower part of the roll is heated, and softening of all layers of the material should not be allowed.
• Modern weldable materials have a protective film on the bottom. This film prevents the layers from sticking together during the storage of the material in rolls. When laying, make sure that the protective film on the surface of the material is completely burnt out. At this point, the heating of this section is completed, since the bituminous layer has reached the optimum temperature.
• After completion of laying, it is recommended to additionally warm up the joints of the material and roll them again with a roller.
• It is allowed to work with gas burners at temperatures up to minus 15 degrees. If it is necessary to work in frost, then oil burners operating on diesel fuel should be used.

So, roofing burners are devices that are necessary for carrying out a number of roofing works. Most often, natural gas or propane gas burners are used, but at low temperatures they are replaced by diesel burners.

When carrying out work on the installation and repair of the roof, there are situations when heating or drying of the material is necessary - for example, when laying a layer of waterproofing or erecting a soft roof, when you need to heat up the bitumen-based mastic. For these and many other purposes, a portable roofing gas burner is used.

With this device, you can perform several types of operations:

• drying surfaces;

• cutting or soldering metal elements;

• firing the old layer of paint;

• other work that requires heating to high temperatures.

The device and principle of operation of the burner

A roofing burner is a metal-based glass equipped with a nozzle and a plastic or wooden handle attached to the body.

The design of the gas burner cup is designed in such a way that the flame is protected from blowing out by the wind.

The flow of gas into the housing is carried out through a special gas pipeline. Mainly pressurized propane is used. The burner has a valve to regulate the amount of gas supplied. In addition, it is also possible to adjust the length of the flame.

In order to save gas consumption, roof burners have a special gearbox that controls the fuel consumption.

Absolutely all models of burners are equipped with an atmospheric air suction system.

To start the burner, use ordinary matches or a lighter.

Gas burners also provide a device for regulating operating modes. For example, most models have a standby mode, the purpose of which is to prevent wasted fuel during work breaks.

Since during operation roofing burners are heated to very high temperatures, only heavy-duty materials are used for their production.

The length of the handle for holding the burner should be no more than a meter. The device itself is very light: its weight ranges from 1-1.5 kilograms.

To prevent burns, the handles of the burners are equipped with a holder made of very durable wood species or heat-resistant plastic.

It should be noted that liquid fuel burners that run on fuel oil or diesel fuel can also be used for roofing.

Stages of work when laying material using a roofing burner

If roofing material is used as a waterproofing material, a gas burner is indispensable. It is also necessary to cover the roof with modern welded types of materials.

The whole process of working with the device can be divided into several stages.

• First you need to prepare the base for further laying the material. To this end, it should be cleaned of debris. If necessary, it is also necessary to level the surface with a concrete screed.

• After that, the roll material is rolled out over the entire surface in such a way that adjacent sheets form an overlap with a width of 85 to 90 mm.

• After completing the alignment and marking, the rolls must be rolled up again and strengthened at the base of the roof with a burner. By heating the lower part of the roll and the base of the roof with the help of a burner flame, the material is slowly rolled out, pressing it to the base.

To avoid the formation of wrinkles and air bubbles, it is necessary to run a hand roller over the attached canvas. At the final stage of work, a roofing gas burner is used to heat the seams of the overlapped material. After that, the seams should be rolled again with a hand roller.

When operating gas burners, you need to know a few important points:

• the use of this device is possible at a temperature not lower than minus 15 degrees;

• if work is carried out at a lower temperature, then you can use a liquid fuel burner;

• when using a gas burner for laying roofing with high quality characteristics, from 500 to 600 m of roofing material can be laid per day;

• since the work is carried out outdoors, the gas burner must provide a stable flame supply and reliably protect it from wind blowing.

Roof burner models

To carry out work on laying the roof, burners of different models are used.

GG-2 is the model name of the propane roof burner. The most suitable sample for self-taught masters performing repairs with their own hands. With high quality, it has a fairly moderate price.

GG-2U has similar characteristics. A distinctive feature of this model is a shortened version of the gas supply tube. It is ideal for work in hard-to-reach parts of the roof, as well as for gluing adjoining and joints.

GG-2S belongs to a series of professional equipment. This model runs on propane. Its main advantage is that the device can be operated even in strong winds. The device consists of two valves and two housings, and this makes it possible to regulate the operating modes with great accuracy.

GGS1-1.7– light weight, size and high performance make this model almost universal. It is used to dry the roof and fuse soft roofing materials on it. It is also successfully used in the implementation of waterproofing and some other types of work, which require a high-intensity flame to bring the surface temperature to 400 degrees.

The burner can be used for work on horizontally located sections of the roof, and on the junctions.

GGK-1– propane-air model. Its difference is a heavier and very durable glass.

This model is suitable for firing old paint, wood surfaces, for waterproofing work. Gas is supplied with a lever.

GGS1-1.0 it is used for small works of small volumes, arrangement of adjunctions. Suitable for operation on roofs with large angles of inclination. Also suitable for laying waterproofing.

GGS1-0.5 used for small repairs on the roof. Differs in economical fuel consumption.

Model GGS4-1.0 equipped with four sockets, which allow simultaneous heating of the roofing material over the entire width and non-stop rolling of the roll.

Due to the presence of special hooks on the edges of the device, heating and rolling of the roofing material can be carried out by one person. Using this model, you can significantly increase the productivity of the work carried out and reduce fuel consumption.

GV-3- a propane torch designed for heating metals, their welding, as well as hand soldering. Cup diameter - 50 mm.

GV-111R used for melting rolled bituminous materials, burning a layer of old paint.

GV-550, GV-900- very easy to use samples. They differ from each other in the maximum length of the flame. The second model makes it possible to work standing up, in full growth, since the length of its torch reaches 900 mm. The first model (GV-550) is more suitable for work at the roof junction points.

The GV model is suitable for heating non-ferrous and ferrous metals, melting rolled bituminous materials during waterproofing and roofing work, as well as a number of other works that require the use of a propane flame only.

GV 500 it is used for the implementation of welded work in the process of laying roofing materials. It can be used to melt bituminous materials. This model can heat the processed material up to 300 degrees.

GV-850- propane burner, equipped with a special valve, which makes it possible to regulate with high accuracy the amount of technical gas that is supplied from the cylinder. The model also has a lever with which the welder controls the length of the flame. This type of gas burner does not work on pure propane, but on a mixture, part of which is technical oxygen.

Safety rules for working with gas burners for roofing

When operating gas burners, safety rules must be strictly observed.

• For roofing work, you need to change into special overalls and shoes with non-slip soles. You will also need some additional devices: navigation bridges, a belt, etc.

• Before starting work, a thorough external inspection should be carried out to make sure that the gas burners, cylinders, connecting hoses are in full working order.

• During the operation of the gas burner, only one gas bottle may be in the workplace. During operation, it is necessary to carefully monitor the tightness of the connection of cylinders and reducers with hoses.

• During ignition of the burner, do not stand in front of the nozzle. The direction of the burner flame must be such that it does not touch nearby people, the gas bottle and the connecting hoses.

• In the process of working with welded materials, it is necessary to ensure that they do not overheat and do not ignite. When heating the material with this device, it is necessary to ensure that only the lower part of the web is melted. The entire thickness of the material must not be allowed to soften.

• The ignition of the burner must not be carried out from accidentally ignited objects. For this purpose, you can use only matches or a lighter.

• When operating a propane burner model, the valve does not open a full turn, but half. After waiting a few seconds, the mixture can be ignited, and then proceed to adjust the length of the flame.

• A worker with a lit burner in his hands does not have the right to go beyond the boundaries of the workplace or climb the scaffolding.

The gas burner is extinguished in two stages:

• shut off the gas supply;

• lower the lock lever.

In the event of a short interruption during operation, the burner must be extinguished. If a longer break is planned, then the gas supply should be stopped at the cylinder.

If the inlet channels of the mouthpieces are clogged, the device must not be operated, as kickbacks and pops may occur.
