[0034] Working principle: When using the device, an external power supply is used to start the servo motor 6 through the controller according to the size of the tower body 11.

The mounting plate 13 moves downward and drives the welding gun 12 to move downward until the bottom of the welding gun 12 contacts the weld. As the tower body 11 rotates, the ring welding work is completed, which improves the welding efficiency of the device.
