The role of welding torches is that in the welding process, the part that performs the welding operation is a tool for gas welding, shaped like a gun, with a nozzle at the front end, and a high temperature flame is ejected as a heat source. It is flexible to use, convenient and fast, and the process is simple, so it is very popular.

What is the role of welding torches?
The welding torch is one of the main equipment for hot air welding. It consists of heating elements, nozzles, etc. According to its structure, it can be divided into gas welding torch, electric welding torch, rapid welding torch and automatic welding torch. The gas welding torch uses the combustion of a combustible gas (a mixture of hydrogen or acetylene and air) to heat the coil so that the compressed air fed into the coil is heated to the required temperature. The amount of air fed in or out is regulated by a cock. The heating device of the electric welding torch is composed of a ceramic grooved tube and an electric heating wire in it. The speed of welding can vary depending on the nozzle configuration. The fast welding torch is made by improving the structure of the welding torch nozzle.
What are the components of welding torches?
The welding torch holds the bolt, raises the bolt (arc lit), pushes the bolt down and transfers the welding current. The welding burner accessories also have a support frame to ensure that the bolt is vertical to the workpiece surface. If the bolt diameter changes, it is necessary to replace the bolt feed with the corresponding diameter and to adjust the length of the drawbar between the support frame and the welding torch body. Provides space for stools of different lengths. The lifting and pressing of the electrode (bolts) of the welding torch is completed by three main components: electromagnetic coil, iron core and spring.
What are the common welding torches?
1. Wire drawing torch
The main features of the wire-drawing welding torchare that the wire feeding speed is uniform and stable, and the moving range is large. However, since the wire feeding mechanism and the welding wire are installed on the welding torch, the structure of the welding torch is relatively complex and heavy, and it can only be carried out by thin welding with a diameter of 0.5 to 0.8 mm. welding.
2. Push Wire Gun
This kind of welding torch is equipped a simple structure and flexible operation, but the welding wire is subject to large frictional resistance when it passes through the hose, so it can only use welding wire with a diameter of Φ1mm or more for welding. According to different shapes, push wire welding torchs can be divided into gooseneck welding torchs and pistol welding torchs.
