The automatic torch is mounted on the welding device directly, so it is not as strict as the weight requirement. Often using larger current and large diameter wire, it has higher requirements on the cooling and current conduction performance. Its structure can be designed according to the construction needs.
The basic structure of the automatic welding torch is the same as the semi-automatic welding torch, but its current carrying capacity is large, the working time is long, and the internal circulating water is sometimes cooled. The welding torch is mounted directly on the lower part of the welding head, and the welding wire is fed into the welding gun through the wire feed wheel and the wire guide tube.
