The welding torch utilizes the high current of the plasma welding machine, and the heat generated by the high voltage is gathered at the terminal of the welding torch to melt the welding wire. The melted welding wire penetrates into the part to be welded, and after cooling, the welded object is firmly connected into one body. The size of the torch power depends on the power and welding material of the welder. The welding torch is qualified in welding effect, safe in welding, fast in speed, reliable in performance of welding torch, simple in maintenance, convenient in adjustment, no need of electricity in welding torch, steel saving, and low equipment investment. Welding gun pressure welding can easily complete the welding work of flash welding and electroslag welding equipment, and the quality and efficiency are better than the latter two sets of equipment.
