[0025] During welding, the pressure inside the collection box 41 is reduced by the negative pressure component 43, which allows the suction pipe 42 to suck the air inside the operating chamber 2 into the collection box 41, so that the scattered welding slag inside the operating chamber 2 is sucked into the collection box 41 for collection, and the air blown out from the outlet end of the negative pressure component 43 is cooled by the cooling component 44, and then the cooled air is blown toward the workpiece through the blowing component 46, which can reduce the high temperature generated by the welding rod and at the same time blow the welding slag generated by the welding rod into the operating chamber 2, so that all the welding slag can be sucked into the collection box 41 to avoid the problem of welding slag falling onto the welding body and affecting subsequent welding work.
