Meanwhile, an annular threaded channel 14 is formed in the side wall of the welding gun 3, and the two ends of the annular threaded channel 14 are respectively connected with the liquid outlet 8 and the liquid inlet 9. The cooling liquid flows in the annular threaded channel 14 for efficient cooling of the welding gun 3. The repair machine host 1 is provided with two connecting ports for connecting the power supply and the pipeline system, and is equipped with a key for controlling the operation of the device for starting and stopping the operation of the device.

[0037] With reference to Figure 2 - Figure 5 , the return water pump 6, the cooling box 4 and the export water pump 5 are sequentially installed on one side of the repair machine host 1. The input end of the export water pump 5 is connected with the cooling box 4, and the cooling liquid is transported to the welding gun 3 through the export water pump 5.
