The outer part of the shell 13 is engaged with the outer part of the driving wheel 16, and the outer part of the driving wheel 16 is rotatably connected to the outer part of the fuselage 3. The inner part of the shell 13 is rotatably connected with a power assembly for providing rotary power. The power assembly includes a worm 14, which is a rod-shaped structure with a spiral tooth shape. The material is a metal material such as alloy steel. The outer part of the worm 14 is rotatably connected to the inner part of the shell 13. The top of the shell 13 is fixedly connected with a rotating plate 15, which is a plate-shaped structure with a certain shape and convenient operation function. The material is a metal material such as carbon steel. The main function of the rotating plate 15 is to facilitate the operator to rotate as the force point. The power assembly is fixedly connected with the driving wheel 16, which is a gear-shaped structure with a certain gear shape. The material is a metal material such as carbon steel.

The welding arc plate 4 cooperates with the fixed arc plate 5 to form a welding area. When the device starts, the current passes through the welding arc plate 4 to generate an electric arc, providing the heat required for welding. At the same time, the cooling pump 11 starts to work, pushing the cooling liquid to flow through the cooling pipe 10, taking away the heat generated during the welding process, thereby effectively reducing the temperature of the machine head. In this process, the heat insulating sleeve 12 effectively reduces the heat exchange between the cooling pipe 10 and the outside, improves the cooling efficiency, and ensures that the device components work normally at appropriate temperature.

[0037] Rotating the rotating plate 15 makes the shell 13 rotate and drive the driving wheel 16 to rotate under the cooperation of the engagement connection. Because the outer part of the driving wheel 16 is also engaged with the driven wheel, the rotating force is transmitted to the driven wheel, so that the welding machine can adjust the welding angle as needed to ensure the accuracy of welding. The whole system realizes the power transmission and angle adjustment of the welding machine through the cooperation of the power assembly and the driving wheel 16, and ensures the smooth progress of the welding operation.
