Dimensions of propane torch for roofing. Gas-burner. The main tool for built-up waterproofing. We assemble in the following sequence

When you need to install a soft roof over a large area, use adhesive compositions becomes unproductive and costly. Some types roofing materials- from the same oxidized bitumen - they are difficult to glue, and the seam at the joints turns out to be unreliable. As alternative way installation, a propane burner is used for roofing works– a tool for installing built-up waterproofing. This device is very effective and versatile, and justifies its use one hundred percent.

Types of gas burners

Of course, there are not only propane burners. There is also a whole classification based on various criteria. Let's look at this in a little more detail.

The principle of operation of a gas burner

Propane burners operate from gas cylinders on which a reducer or other gas distribution device is installed. With a small amount of work, propane cylinders can be installed on the roof; in other cases, they are placed lower, connecting to the burners through hoses, the length of which should not exceed 15 m.

Torches are used not only for connecting rolls waterproofing materials, but also other tasks. For example, for dismantling an old roof, removing paint, heating metal pipes before welding, heating hardening bitumen, and so on - the equipment is multifunctional.

Interesting to know! Propane burners are devices that use flammable, explosive mixtures. Therefore, industrial production of these devices is allowed only in accordance with the technical standards established by GOST 17356-89.

The state standard regulates the following technical indicators:

• shut-off devices that control the gas supply must be completely sealed;
• propane must be supplied smoothly to avoid the possibility of explosion;
• devices must be equipped with wind protection to prevent arbitrary flame extinguishing;
• it is required that the device switches off reliably within a certain time;
• thermal power limits have been set.

Gas burner design

Now let's look at how a propane burner works - what components are there and what they are intended for. As an example, consider a combined gas-air burner that sucks in air from the surrounding space.

1. Fuel preheating chamber– a container inside of which an electric heating element is installed with the ability to regulate the strength of the current supplied to it. This unit can be installed optionally, for example, when it is necessary to perform work with negative temperatures air.
2. Burner body– this part of the device is made of heat-resistant steel, in which the fuel stream is mixed with air.
3. Nozzle– the element is connected to the body through a union nut that has a hermetically sealed seal.
4. Control valve– a unit that controls the propane pressure value at any time. It is worth noting that during long breaks the gas supply will be turned off automatically.
5. Extension tube- enters it flammable mixture from the stream separator. The last part is installed immediately behind the nozzle.
6. Mouthpiece– the shape of this element determines the width of the combustible mixture at the exit from the nozzle. It is also designed to protect the flame from the wind.
7. Control valve– regulates the supply of the combustible mixture, and accordingly the length of the flame escaping from the nozzle.
8. Pen, made of heat-resistant plastic, allows you to operate the tool with convenience and safety.

In addition to the above, the delivery package may include additional parts. For example, a set of sealing paronite gaskets, a replaceable injector, a connecting clamp for the cylinder.

Interesting to know! A cylinder for a propane burner is purchased separately. Most devices are designed for use in conjunction with 50 liter cylinders welded from steel. Technical standards for these cylinders are established by GOST 15860-84, which is still in force today.

For use gas-air burners A one-stage reducer is also required for the cylinder, which will ensure normal pressure of the supplied fuel. You also can’t do without a rubber hose. combined type. The product class is first, according to the even older GOST 9356-75. The hose must have a thread braid and be 9 mm in diameter.

How to use the burner

The roofing burner is used in the following sequence.

1. Before starting, it is imperative to check the tightness of the sealing gaskets. For this purpose, it is necessary to pass air through the burner.
2. If a leak is detected, the O-rings must be replaced with new ones, coated with sealant. After this procedure, the burner can be used no earlier than a day later.
3. When starting, the first thing to do is open the air supply valve, then the gas supply valve. Next, using the existing ignition system (piezoelectric element, lighter, match), the combustible mixture at the exit of the nozzle is ignited.
4. The divider moves to adjust the sufficient length of the torch, and its width is adjusted with the mouthpiece.

Advice! If necessary, an adapter-socket for several working nozzles is installed on the mouthpiece.

Turning off the burner is carried out strictly in the reverse order.

How to choose the right burner for roofing work

First of all, it is necessary to evaluate all the important operational characteristics of the device, which include:

• gas consumption, kg/h;
• output power, kW;
• the maximum possible width of the heated section of roofing felt or other roofing material used for the device soft roof;
• possible limits of flame (torch) length, mm;
• nominal temperature heating of the surface, °C;
• fuel consumption in kg/m2 laid surface;
• device weight.

Of course, everyone will look at the characteristics that are most important to them, but first of all you should still pay attention to the ease of use of the equipment. The simplest example is that if you try to work for a long time with a burner that weighs 1.5-2 kg, then your hand will get tired quite quickly, and the work efficiency will decrease significantly. Using the same reasoning, you can determine the length of the torch - usually they focus on a value of 300-900 mm. With the maximum length, you can safely work with the burner while standing.

A number of characteristics should be selected according to the heat capacity of the soft roof being laid. For example, for ordinary roofing felt it is required working temperature 160-180 degrees, whereas for surfaced materials this will not be enough, because their operating temperature is 300-350 degrees.

Burner performance can be calculated using a very simple formula, which involves the following quantities: W – thermal power equipment; V – fuel consumption; Q is the calorific value of propane, which is equal to 18.88 kWh/kg; n – the number of nozzles (nozzles) through which the flame is directed to the object being melted (heated), also known as the roofing material; η = 0.8...0.91 is the efficiency of the heating process itself (this parameter will decrease with an increase in the number of active nozzles).

The formula itself looks like this: V = W/Qnη.

Is it possible to make a gas burner yourself?

Now let's discuss the possibility self-made propane torch. Of course, all this is feasible, however, due to the requirements for sealing all parts, as well as the high precision of their manufacture, doing this in practice becomes very difficult. And if you take into account the low cost of factory-made devices, then this makes no sense. The most important part of the assembly work is the manufacture of the fuel supply and mixing unit, so spare parts from other devices are often used for such work. Let's try to describe the self-assembly process.

The diagram above shows the approximate structure of a propane burner - we have already discussed the main structural elements. When assembling, we will not make everything, and we will use spare parts from other equipment that you may have in stock. We will need:

• valve made of steel - you can take it from any cylinder intended for storage liquefied gas;
• plug - it is usually used when transporting gas cylinders;
• from blowtorch we will borrow a jet, the nozzle of which should be 0.8 mm;
• You will also need a metal pipe - its internal diameter should be 10 mm, and the wall thickness should be at least 2 mm;
• wooden handle – you can make this part yourself.

Now let's look at our steps at work:

• steel pipe, which we will use as a supply tube, is secured in the handle. This can be done using glue;
• We make the body and divider from a brass rod with a diameter of 20 mm. In the body you need to drill two radial holes with a diameter of 5 mm, 4 holes are made in the divider rod (diameter - 1 mm);
• assembly is carried out - the divider is pressed into the body with great interference. A flange is installed inside the housing with a gap so that the internal diameter of the housing is 0.6 mm larger. The gap thus obtained will inhibit the gas flow supplied to the igniter holes;
• a nozzle must be machined from a steel rod;

Advice! To make in metal thin hole, take a 2 mm drill and make a blind hole so that the tip does not reach the end of the metal 1.5 mm. A 0.4mm drill bit is then used to make the bridge. Next, the resulting hole is caulked with a hammer, after which the end is sharpened with sanding paper. This is done until a hole of the required cross-section is obtained, that is, until the nozzle can be placed on the tip of the threaded tube.

• a supply hose is put on the rear end of the tube and secured with a metal clamp;
• the operating pressure is set on the reducer and gas is supplied;
• wait until all the air comes out of the hose, then ignite the gas, bringing it into the flame of the gas burner;
• After this you need to sand the end. The flame on the burner should be 5 cm long;
• the housing with the divider is put on the external thread of the nozzle. The burner should produce an even flame without soot - to achieve this effect, you need to slowly rotate the body along the threads on the nozzle;
• free threaded connection sealed with FUM tape.

That's all. We hope the material was clear and useful for you.

To carry out repairs and other roofing work that involves melting mastics and laying roofing materials, you will need a special gas burner. The device is primarily used to perform 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 enough simple design. It is a glass made of metal and equipped with a nozzle and a handle, which is attached to the body . Heat-resistant plastic or wood can be used to make the handle. Gas enters the housing passing through the gas pipeline. In most cases, propane under pressure is used to operate the burner.

The burner glass should have a shape that protects the flame from being blown out by the wind.

There is a valve on the burner body that allows you to adjust the flame length and intensity of the supplied gas. It’s good if the burner has a reducer, which allows you to use gas economically.

Roof burner components

During the assembly process of the device, mechanical processing is practically not used. The burner is assembled from ready-made spare parts. To make it we will need:

1. A steel valve that can be taken from a cylinder intended for storing liquefied gas.
2. A plug used for transporting gas cylinders.
3. A nozzle 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.

You can use the handle from a burnt-out soldering iron as a handle.

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 secure it with glue. The divider and body must be machined from a brass rod, the diameter of which should be 20 mm. In the finished body, two radial holes are drilled (each diameter is 5 mm) and four holes are drilled in the divider rod (each diameter is 1 mm).

When assembling, it is necessary to press the divider into the body with a slight tension. At the same time, the flange must be installed inside the housing with a gap, that is, the internal diameter of the manufactured housing must be 0.6 mm larger. diameter machined The resulting gap is responsible for the inhibition of the gas flow, which is supplied to 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. doesn't reach the exit. Drill with a diameter of 0.4 mm. used for jumper. The resulting hole must be completely caulked with gentle hammer blows. Then you need to sharpen the end. For this we take sanding paper and sharpen until the desired cross-section of the outlet hole is found, that is, until the nozzle can be placed on the tip of the threaded burner tube.

A supply hose made of fabric-rubber material must be attached to the end of the gas supply tube. Secure the hose to 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 insert the nozzle into the flame of the gas burner.

The past decade has been characterized by the emergence of revolutionary changes in the technology of arranging soft roof coverings. Classic roofing felt has given way to modern built-up materials. The composition of the tools needed to perform roofing work has also changed. Bucket of bitumen and brush replaced roof burner.

What kind of equipment is this?

Gas-burner– irreplaceable hand tool to perform work on the installation of soft roof coverings using modern weld-on materials. The flame torch formed by a working burner allows you to create local heating of the surface to perform the following operations on the roof:

• drying wet areas of the underlying surface;
• heating and melting of the lower bitumen layer of the welded roll material.

In addition to performing work on the roof, the roofing gas burner is used:

• for heating to the required temperatures various products and materials;
• when soldering metals with light alloy solders;
• for burning old paintwork.

Design and principle of operation of the burner

The roofing gas burner includes the following elements:

To operate the burner you will need the following additional equipment:

• liquefied gas cylinder;
• gas reducer - reduces the gas pressure from the cylinder to the working pressure (0.1 - 0.15 MPa), stabilizes the gas flow in the burner;
• flexible hose – connects the burner to the output of the reducer.

The weight of the burner is small, no more than 1 - 1.5 kg. Many models have the ability to switch to standby mode, when during short breaks in operation the gas supply is reduced to a minimum that allows the flame not to go out.

A convenient option that saves gas and eliminates the need to re-ignite the burner after breaks in operation. To ignite the burner, it is usually used external source flame: matches or lighter.

Roof burner models

• GGS-1– the simplest and most popular model. Flame length 600 mm. Versatility and low weight determine a wide range of applications.
• GG-2– basic model of a gas burner. It has an excellent price-quality ratio. An excellent choice for DIY roof repairers.
• GG-2U– the model is similar to GG-2, differs by a shorter main tube. Convenient to work in hard to reach places.
• GG-2S– the beginning of the professional series. The burner is designed to operate in strong winds.
• GGK-1– has a weighted glass and a trigger gas supply mechanism.
• GGS-4-1.0– has 4 glasses, simultaneously covering the entire width of the roll with flame. Significantly speeds up work on large volumes of roofing work.

Application of gas burners

The gas burner is practically an indispensable tool during roofing works using fused materials. A well-chosen high-quality burner allows a team of two people to lay up to 60 rolls of weldable material in one daylight.

When performing work with an open flame Special attention must be given strict adherence to all rules fire safety. So, if the area covered by the infection exceeds 500 square meters, a prerequisite is the presence of fire hoses at the site.

There must be access to the hoses from all four sides of the surface to be covered and the possibility of spilling water at any point of the laid covering.

Stages of work when laying material using a roofing torch

Work on arranging the roof with rolled fused materials is carried out in several stages:

How to make a gas burner with your own hands?

Today, manufacturers offer a huge range of gas burners that can satisfy almost any user. But there are times when homemade instrument takes its rightful place in the home workshop.

Making a gas burner with your own hands is quite feasible at home. If for one reason or another you cannot buy or make a burner, you can rent/rent it.

What you will need for this:

• Gas jet with a nozzle passage diameter of 0.8 mm. The easiest way is to pick one up from a used car carburetor. Home gas stoves are often equipped with a set of additional jets.
• Gas line - copper or brass tube 70 - 80 cm long. The diameter and thickness of the walls are selected so that it can be cut from one edge internal thread to secure the nozzle.
• Wooden or plastic handle. Wide choose options. It should be beautiful and comfortable.
• The glass is the body of the burner and protects the combustion zone. You can pick up a piece of thin-walled metal pipe length 100 - 140 mm, internal diameter 25 - 40 mm. Can be made from sheet metal 0.8 - 1 mm thick. Connect the edges by welding or using rivets. Manufacturing materials: soft iron, copper, brass.
• Control valve. Perhaps the most difficult issue is in the design. It should easily shut off the gas and be convenient to use. You can search among the plumbing fittings, or you can pick them up from a used home gas stove.
• Gas cylinder, reducer, flexible hose. There is no need to invent anything, just take something ready-made. These elements directly address issues of safe operation.

We assemble in the following sequence:

1. In the gas line pipe On one side we cut the internal thread and screw in the nozzle.
2. We attach a glass to the same side of the tube from the outside. We use three spacers from available material.
3. Drill a hole in the handle, insert the other end of the gas line into it and fix it with glue.
4. We connect the output of the control valve with the end of the line protruding from the back of the handle.
5. We connect the input of the control valve to the flexible hose, fix it with a clamp.
6. Connect the second end of the flexible hose, gearbox, gas cylinder.
7. Let's turn on the gas and wait for now the gas will displace the air in the hose.
8. Set it on fire, adjust it the required flame length.

When making a burner with your own hands, you must remember that a gas burner is a high-risk tool. Consider every transaction carefully. It is necessary to exclude the possibility of gas leakage when operating a homemade burner.

Safety rules when working with gas burners for roofing

Carrying out work on the roof using a gas burner affects several areas of labor protection:

• work at height;
• work carried out with open fire;
• handling of flammable substances.

Use, strictly observing safety precautions, is the basis for preserving human life and health.
Accordingly, the entire range of security measures can be divided into three parts.
Measures to prevent a worker from falling from a height:

• the presence of shoes that prevent the worker from slipping off the roof surface;
• safety devices to prevent falls from a height;
• presence of fencing of the working area, walking walkways, etc.

Measures to protect workers from exposure to elevated temperatures:

• availability of special clothing, gloves;
• Do not direct the flame towards people or elements of the gas installation;
• You must not leave the work area or climb scaffolding with a lit burner in your hands.

Fire safety measures:

• ensure availability in work area primary fire extinguishing agents;
• work with an open flame can be performed during daylight hours in the period from 8 to 18 hours;
• no more than one liquefied gas cylinder can be in the work area at a time;
• it is necessary to exclude heating of the gas cylinder;
• Avoid overheating and ignition of the deposited material.

Before starting work it is necessary to inspect gas equipment and make sure it works. Check the tightness of the connections of the cylinder, reducer, hose and burner.

conclusions

Practice shows that to successfully complete any work, two main tasks must be solved:

1. carefully and comprehensively study the subject of the work to be done;
2. choose the right tool.

Knowledge gives 50% of success in the upcoming work, and a high-quality, wisely selected tool – 80%. Take action, everything is in your hands!

Roofing technology soft materials provides for the laying of roofing felt made of roofing felt, possibly either in a non-fire method, using special solvents and fixing liquids that melt the bitumen layer of the coating, or in a fire method, when the surface is heated using a gas burner and the roofing felt is literally glued to the roof.

When using the fire method, appropriate equipment is also used for fast, efficient and mobile equipment movement along the roofing surface - gas burners.

In addition, they also carry out other roofing work:

1. Preparatory– drying surfaces in inclement weather.
2. Additional– old paintwork is burned, metal is heated or cut.
3. Repair– the area where the coating is damaged is precisely heated and compacted.

Description, device and principle of operation

Gas burners are inherently- These are portable torches that burn a mixture of propane-butane and air. Structurally, all manual gas burners consist of a metal cup, inside of which there is a gas nozzle on a long tube, with a plastic handle or handle made of wood with a regulator or tap to adjust the gas flow.

Gas is supplied from a cylinder through a hose under pressure.

The operating principle of the burner can be represented as follows:

1. Pressurized gas is supplied through a hose to the tap on the burner.
2. By opening the tap, the gas flow to the burner nozzle is regulated.
3. A lit nozzle delivers a flame through a glass to the heated surface.

Most hand-held roofing torches are ignited with a match or lighter, but more modern types The instruments are equipped with piezo ignition, which makes working with them much easier. The design of the glass is designed in such a way that it has air leaks, and the lit flame is not blown out even by very strong gusts of wind.

Manual gas torches are mainly used for roofing work. But at the same time, the scope of application of the tool does not end there; such a tool can be successfully used in other construction projects. installation work ah, where rapid local heating of materials is necessary, for example, when laying pipelines, waterproofing welded joints, when removing various coatings, when heating the bitumen mixture in road work.

Advantages and disadvantages

A manual roofing torch, today, is essentially the most effective tool when carrying out roofing work on soft surfaces.

This is largely due to the fact that:

1. It has a small weight, on average about 1.1 kg.
2. The regulator allows you to easily adjust the length of the torch.
3. A comfortable handle made of heat-resistant plastic or wood allows you to work for a long time.
4. The length of the burner allows you to heat the rolled coating without unnecessary movements.
5. A special limiter will prevent the nozzle from coming into contact with the roof covering.

The disadvantages include:

1. Small radius of work, depending on the length of the gas supply hoses.
2. It is difficult to carry out work at low temperatures - the propane gas mixture thickens, creating difficulties with ignition and adjustment of the flame.
3. Quite a large gas consumption during work.

Kinds

To perform installation work on laying roofing from rolled materials using the fire method, we use different kinds gas burners with their own specifics and purpose.

Small class burners GG-2

In most ways, it is used for small-scale work or in the household. This is related to small in size burner, its gas supply tube is slightly shortened. But at the same time, this is a big plus when working in hard-to-reach places - for example, when laying coating on air ducts, or repair work on small areas using small cylinders.

Burners type GG-2S

Has two housings, which allows you to achieve more high temperature , and the valve available for each nozzle allows you to regulate the gas supply and find the best option.

GGK1

Specially produced for heavy-duty work and is characterized by increased reliability and durability, although it is somewhat heavy.

GGS1-1.7

Widespread due to its light weight and relatively economical gas consumption.

Burners type GV

Both the GV-900 model and the GV-550 model have become widespread due to the ability to heat surfaces in full height, while in the GV-900 models the flame torch can reach 900 mm, and in the GV-550 model - more than half a meter.

Roof roofing technology

Soft roofing technology roll materials by fire, produced in several technological stages:

1. Preparatory stage: Preparation concrete base, sealing cracks, removing debris.
2. Roll base layout, connecting joints, gluing joints.
3. Strengthening the foundation planting it on a bitumen base.
4. Using a manual gas torch, the base is heated and the roll covering is laid, pressed with a roller and the joints of the rolls are additionally treated with mastic.
5. Using a torch The base and the first layer of coating are heated, and the top layer is laid.

Safety precautions

The basic safety rules when working with a manual gas roofing torch are: general rules carrying out hot work.

Special rules include the rules gas safety, namely:

1. Gas cylinders must be in good working order, have no visible defects and have the appropriate seal of suitability for use.
2. Hoses must not have mechanical damage, cuts, cracks.
3. Connections, including hoses, reducers, and burners must be sealed to prevent gas leaks.
4. Smoking is prohibited while working.
5. Gas roofing burners cannot be used at temperatures below minus 15 degrees Celsius, this risks causing the gas cylinder to explode.

Best models

Roof burner GGS1-1.7

Has two flame modes - working and standby, equipped with a control valve, burner weight – 880 grams, average gas consumption of about 9 liters per hour.

The price ranges from 1500 -1900 rubles.

GV 3 R

Unlike other types, it has lever control, weight about 1 kg.

Price 250-350 rubles.

GV – 900

Professional tool, equipped with piezo ignition, has a lever control, length 900 mm, weight about 900 grams.

The average price is about 1600 rubles.

DIY making

The gas burner itself is a very complex and responsible device. When making it, you need to use not only knowledge of metallurgy, because when heated, propane heats the surface to almost 1500 degrees.

You also need to ensure the tightness of the connections of all parts, including metal ones, and here you can’t do without turning. In addition, the nozzle itself for the exit of the gas-air mixture must be of a certain diameter, and achieving such an indicator at home is almost impossible.

Another way to make a gas burner is to use a nozzle from a gas welding torch as a working body, a glass can be made from an ordinary pipe, wooden planks can serve as a handle, and a water valve can also be used.

WITH It is better to make a gas tube from brass, in as a last resort, black metal, but in this case it must be thin-walled for rapid cooling by ambient air.

At the slightest sign of a gas leak, immediately stop work and turn off the unit, turning off the gas supply both to the burner itself and to the gas cylinder reducer valve.

Under repair roofing coverings with the need to use hot air and even fire, you often have to: melt the bitumen, melt the underside of the roofing material and even solder the edge metal sheet. And for this you already need special tools. But why not just set the same roofing felt on fire with a homemade torch if our goal is to melt the bitumen?

The fact is that you won't succeed this way. How do you direct the fire in the right direction, especially when there is wind? And how long will such torches last, since the work of laying the roof will be serious? These two main functions are performed by a gas burner. And now we’ll tell you how to choose it.

A gas burner is an indispensable thing when repairing a roof. It not only lays sheets of roofing felt, but also heats up the mastic and even seals small seams and holes. Here full list all operations:

• Cutting and soldering of metal elements.
• Removing the old layer of paint.
• Sealing small cracks.
• Melting mastic.
• Heating sheets before laying.
• Strengthening butt seams.

A typical roofing gas burner consists of a comfortable handle, a tube that supplies gas, and a metal cup at the end. A hose is connected to a special connector on the handle, and the required amount of gas is supplied to it from the cylinder. And you need to regulate the pressure through the valve on the reducer.

In practice, everything is simple: we press the handle lever, the gas enters the hose, and at the outlet of the glass, a combustion of a mixture of gas and air is formed, which we first ignite with a match. The flame temperature is so high that it can reach 1500°C! Using a valve, you can regulate not only the strength of the flame, but also its length.

Conventional gas burners are light enough - within 1-1.5 kg - so that you can easily hold them in your hand and not drop them from fatigue. And the role of the glass is precisely to shape the flow of flame in the desired direction. The design of the glass is precisely shaped in order to maximally protect the flame from being blown out by the wind. Moreover, both the glass and the pen different models burners are made differently. Although they have the same operating principle: starting a gas burner is no more difficult than a kitchen burner - using an ordinary match or lighter.

Almost all modern gas burners for roofing provide a means of adjusting operating modes: standby mode and operating mode. The standby mode is designed specifically to save fuel.

Different models of modern gas burners differ from each other primarily in the principle of mixing air into the gas. Older burners are connected to an oxygen cylinder, while modern ones can take air from the atmosphere, which is more convenient, of course. Even the gas the burners use can vary. There, most often propane is used, but there are also units that run purely on methane. But we will also note other differences, based on which you can make the right choice.

Standard gas burner in action:

Which is better quality: professional or budget?

So, professional contractors purchase usually expensive professional gas burners that are reliable and safe to use. But for the home craftsman for equipment and roof repairs own home a small one will do handy tool without additional claims. Will the quality of work be worse? Not at all! It’s just that such a gas burner is not suitable for industrial work, where it is used almost every day and where uninterrupted processes and absolute safety come first.

It is also not acceptable to have a situation where a team goes to a new facility (and, of course, deadlines are definitely running out), and the burner is defective. There is neither time nor reserve to stop everything and go out to purchase new equipment. Whereas with careful handling in the hands of home handyman even the most Chinese unit will serve faithfully for decades. Especially if you use it no more than once a season.

And in the end, when working with a massive professional burner or with a regular one, you will get the same result. But no matter how expensive and professional a gas burner is, be sure to check it before each use connecting hose, tightness of joints and clogging of the mouthpiece. Such problems do not occur often, but if you miss a defect, there is a risk of serious consequences.

Although, if you have an idea to buy the cheapest “lighter” (how much does it cost to cover a garage roof?), then we will hasten to dissuade you. The fact is that if a gas burner has a weak gearbox, then the fire will be no more useful than the same blowtorch. The work will proceed extremely slowly - while you heat one part of the sheet, the second will already have time to cool down. As a result, you will simply have to remove the gearbox and work without it at your own peril and risk.

Which is safer: compact or large?

At first glance, it seems that hauling a gas cylinder onto the roof is the most dangerous undertaking. Moreover, today you can purchase more compact versions of gas burners:

But in fact, it is precisely these cans that can cause burns and even fire. We are talking about counterfeit Chinese products, which are abundant in the construction market. A large cylinder is still located far from the operating burner, while a small cylinder is constantly in the high temperature zone, which is not at all safe. Decide for yourself!

One more point about safety. When choosing a gas burner for your roof, try to avoid counterfeits and overly cheap products - this is simply unsafe. So, the most common problem with such burners is that the operating pressure may be indicated in the technical data sheet as 0.05-0.08 MPa, but in reality it turns out to be up to 1.6 MPa, as in any propane burner. But the supplied gearbox is not at all designed for such parameters, and a closed valve may not withstand the pressure directly on the roof. Such a burner requires a gearbox, but an inexperienced user may simply not know about it.

Which is more convenient: long or short?

If you value ease of use, then purchase a lever roof burner, in which you do not need to constantly tighten and unscrew the valve. But how long should the handle be?

Thus, the length of the burner is not a style, but an important functional point: short ones, which do not exceed half a meter in length, usually make partial repairs, heat up individual areas and melt the necessary areas of the roof. But for larger-scale work, you will need a burner with a length of at least 80 cm.

How to make a gas burner yourself?

Like any other tool, you can also build such a burner with my own hands, if you are confident in your continued safety. But remember, a gas burner is a complex device, and it is important to follow all the rules.

In order to make a torch, you will need a divider and a metal rod - attach them to a handle made of special heat-resistant wood. Borrow a gas supply hose from the gas welding system. And finally, examine the unit for the slightest gas leaks - this is important!

Or everything can be done simpler for small roofing repairs (the result is a fairly powerful burner, note):

Obviously, it is better to buy a ready-made gas burner with all the certificates than to even entrust its manufacture to a friend good master. Just when purchasing, pay attention to the material used to make the burner – only high quality! After all, any burner heats up to a fairly high temperature, and therefore the material must be ultra-strong. Next, look at the handle - it should be equipped with a holder made of durable wood or heat-resistant plastic. This is important if you don't want to get burned unexpectedly while working.

That's all the subtleties!
