Oxygen-free gas welding is gas welding

Oxygen-free torch does not require a specialized oxygen cylinder, the use of natural air in the oxygen and gas bottles of combustible gases in the phase mixing combustion, jet formation of heat source the highest temperature can be up to 2400 degrees.

Compared with the traditional oxygen torch, oxygen-free torch without oxygen cylinder, it is only a gas bottle and a welding torch, especially suitable for refrigeration and air conditioning heat pump equipment, copper pipe welding and installation and maintenance, easy to carry, easy to operate and reliable features.

When soldering copper pipes, you only need to bring a can of Mighty Fire Gas (Manpower Gas) and an oxygen-free torch to work (no oxygen cylinder). A bottle of Mighty Fire Gas gas weighs about 453g, according to the Mighty Fire brand double-barrel oxygen-free welding gun maximum gas consumption 9g calculation, a small bottle of Mighty Fire Gas gas can last for 50 minutes; if you use Mighty Fire brand single-barrel oxygen-free welding gun can be continued to weld for more than 1-2 hours.

As the saying goes, "It's a mule or a horse that comes out for a walk", and the welding effect of the oxygen-free torch will be known once it is tried. We tested two types of oxygen-free welding torch, the clip effect is as follows: As you can see through the video, we are on the φ28 purple pipe welding, whether it is a single tube or double tube oxygen-free welding torch are able to weld. Relatively speaking, the double-tube oxygen-free welding torch is more efficient in burning heat, and is suitable for use in occasions with large pipe diameters and large spaces. If it is a small pipe diameter of narrow space, you can use a single tube is more appropriate. Twin Tube Oxygen-free Torch + Hook + Connection Tube

Use the Oxygen-free Torch to weld with the inner flame tip, do not weld the gas cylinder upside down.
