[0030] In the present invention, a housing 11 is provided on the top rear side of the bottom plate 10 , and the fan 12 , the coil 13 and the support block 22 are all covered in the housing 11 , and the interior of the housing 11 is cooled by the provided fan 12 .

[0031] First, a power cord 110 is provided on the rear side wall of the shell 11, an open groove 111 is opened on the front side wall of the shell 11, a power switch 112 is embedded on the right side wall of the shell 11, and a handle 113 is welded on the top of the shell 11. The power switch 112 is used to control the power of the welding machine body 1, and the handle 113 is provided to facilitate the picking up of the welding machine body 1 and the use thereof.

[0032] Secondly, the power switch 112 is electrically connected to the power line 110 , the fan 12 , and the coil 13 through wires, so as to ensure the normal operation of the fan 12 and cool the coil 13 .

[0033] Specifically, a first T-shaped threading column 150 is inserted into the first electric shock block 15, and the first welding wire 130 is inserted into the horizontal end of the first threading column 150. The top of the vertical end of the first threading column 150 is threadedly connected with a screw head 151.

Finally, the welding frame 20 is driven from the position of the switch 201, and the drive switch 201 is turned on at the same time. The welding frame 20 slowly moves downward toward the welding plate 14, so that the copper core welding head 212 is aligned with the welding area at the top of the object to be welded. The copper core welding head 212 and the screw head 151 are in contact with the object to be welded at the same time and generate electric shock, so that a welding spot is formed in the welding area of ​​the object to be welded. After the object to be welded is fixed, the welding frame 20 is released, and the welding frame 20 is reset with the action of the torsion spring 222.
