The switching mechanism 2, two fixing mechanisms and the protective plate 3 are used to isolate the welding position from the staff, thereby effectively avoiding spatter and high temperature that may be generated during the welding process, protecting the safety of the operator, and the design of the transparent protective plate 3 is convenient for observing the welding process, and abnormal conditions in the welding process can be discovered in time. When the welding point position needs to be adjusted according to the size of the workpiece 32 to be welded, the adjusting motor drives the adjusting screw 19 to rotate, and then drives the adjusting frame 18 and the movable frame 22 to move in the front and rear directions, thereby realizing the position adjustment of the upper electrode rod 26 and the lower electrode rod 24, so that the tooling can adapt to the welding requirements of components of different sizes.
