Do you want to learn how to make a burner with your own hands at home? I offer 2 instructions at once: assembling a conventional burner for laying roofing materials and making a high-temperature cutter. Having made tools according to the proposed schemes, you can heat roofing bitumen, melt tin and cut fusible metals.
Everything you need to know about gas burners
- Gas-burner (acetylene or propane) is a tool with which you can get a flame with a variable flame temperature and flame size;
- conventional propane torch - this is a nozzle with a regulator connected to a gas supply under pressure;
- Acetylene torch - This is a cutter for which an oxy-fuel mixture is used.
Using gas under pressure as a fuel, it will not be possible to obtain a high temperature. But, if you mix propane with oxygen, the temperature of the flame increases significantly.
The figure shows two types of burners:
- Injection — due to the higher pressure, oxygen sucks in the gas and sends it to the mixer;
- Injectorless - oxygen and gas are supplied separately, but with the same pressure.
Non-injector cutters are structurally simpler than injector burners. But injection cutters, due to the high pressure of the fuel mixture, are used in welding and cutting metals.
There is also an infrared gas burner, but it does not apply to cutting tools, but to heaters. The heating element for uniform distribution of heat is located with the emitter to the top and transforms thermal energy into infrared radiation. Adjustment of temperature and intensity of heating is carried out by a tuning valve.
We assemble a burner for laying roofing felt in 10 minutes
For assembly you will need:
- Nozzle and faucet from an old gas stove (both parts can be bought on the construction market. The price is cheap);
- gas cylinder (you can get by with a camping cylinder with a volume of 10-20 liters);
- Connecting hose with slip-on clamps.

 | Connecting the nozzle to the faucet. We connect the valve through the nozzle to the nozzle. |
 | We connect the gas cylinder to the burner with a hose. The connections must be tightened with collar clamps. |
 | Trial run. With the tap on the burner closed, open the supply from the cylinder. We bring a lit match to the nozzle and open the gas supply valve. |
 | Torch adjustment. The flame flow is regulated by turning the valve: counterclockwise - more, clockwise - less. |
A home-made gas burner is no worse than a purchased tool in terms of efficiency and safety of use. I am sure that the tool, assembled according to the proposed instructions, will be useful to you.
Assembling a portable cutter for the home workshop
This compact tool, despite its low power, gives a flame with temperatures up to +1000°C. To make a gas burner at home, we need the following materials:
- Pumping needle for inflating balls;
- A thin needle from a disposable syringe;
- Plastic bottle with a volume of 1.5-2 liters;
- Two sets of droppers with clips;
- Copper wire with a diameter of 0.5 mm;
- Flux and accessories for soldering;
- Nipple from a bicycle or car camera;
- Hot glue and gun.
The wiring diagram shows a portable torchless torch.Next, I’ll tell you how to make a tool with your own hands according to the proposed scheme.
| Illustration | Stage description |
 | Making a hole in the needle. Stepping back from the end of the needle 10 mm, we make a transverse incision with a triangular file, so that a small hole forms. |
 | We bend the needle. The needle from the syringe, with the help of pliers, is bent at an angle of 135 °.
. |
 | We grind the sharp edge of the needle. We grind the curved needle on a file or grindstone, so that there is no point left.
The length of the needle section from the fold to the ground end should be equal to the length from the end of the thick needle to the hole made in it. |
 | We connect the needles in one knot. A thin bent needle is pushed into the hole. As a result, the end of a thin needle should protrude from a thick needle by no more than 1 mm. |
 | Winding copper wire. The area where the thin needle enters through the side hole into the thick needle is wound with copper wire. We make the winding turns as close as possible to each other. |
 | Flux processing. We process the winding made with flux before soldering. Do not use rosin, as when working with flux, the solder sticks better. |
 | Soldering. We solder the wire winding with tin solder. We heat the turns with a soldering iron so that the solder passes to the needle. As a result, the soldered area of \u200b\u200bthe connection of the needles must be completely sealed. |
 | We connect the assembled mixer. We connect 2 dropper tubes to the previously assembled assembly. One tube is connected to a thin needle and the other to a thick needle. On the dropper tubes, next to the mixer, we put on clamps, one for each tube. |
 | We fix the clamps. We glue the clamps together with hot glue, so that the adjusting rollers are located on the outside.
. |
 | Joint sealing. We glue the soldering area and the dropper connection areas with hot glue. Thus, we will ensure the tightness of all connections. |
 | We pass the dropper tube through the plastic cap. A hole is drilled in the cork of a can for refilling lighters along the diameter of the dropper tube. A tube is threaded into the hole. |
 | We connect the handset. One of the nozzles that comes with the gas cartridge is tightly inserted into the tube.
We pull the dropper tube through the stopper. We do this so that the nozzle fixed on the tube rests against the opposite side of the cork. |
 | We apply sealant. We seal and strengthen the connection with hot glue. Now, if you put the cork on the cylinder, the nozzle will press on the fitting and the gas supply will begin. |
 | Installing the compressed air connection. At the bottom of a plastic bottle with a volume of 1.5-2 liters, we fix a metal pipe with a check valve.
As a pipe, you can use a nipple from an old bicycle or car camera. |
 | Installing the burner connector. We attach a connecting pipe to the cork of the bottle to connect the dropper from the burner. |
The burner, receiver and connecting hoses are ready, it remains to connect all the elements together.
We connect the tube from the cap of the gas cartridge to a thick needle. We connect the tube from the receiver bottle to a thin needle.
We attach the pump to the receiver nipple and pump up 2-3 atmospheres.If there is no pressure gauge on the pump, pump according to the sensations. We put a cap with a tube on the gas cylinder.
The do-it-yourself burner is assembled and ready for use. How to use it?
- We loosen the clamp on the gas supply;
- Ignite the gas from the end of the needle;
- Gradually loosening the clamp with air, we get the same flame as in the photo.
