[0002] Spot welding machine is a mechanical device that adopts the principle of double-sided double-point overcurrent welding. When working, two electrodes pressurize the workpiece so that the two layers of metal form a certain contact resistance under the pressure of the two electrodes, and when the welding current flows from one electrode to the other electrode, an instantaneous heat fusion is formed at the two contact resistance points, and the welding current instantly flows from the other electrode along the two workpieces to this electrode to form a loop, and will not damage the internal structure of the welded workpiece;

[0003] For example, the Chinese authorized patent (pneumatic spot welding machine) with announcement number CN220560641U: including a spot welding machine body, a protective mechanism is installed on the left side of the spot welding machine body; the protective mechanism includes a frame, the frame is fixedly installed on the left side of the spot welding machine body, a motor is fixedly installed on the top of the frame, a threaded rod is fixedly connected to the output shaft of the motor, the external thread of the threaded rod is connected to a lifting block, the front of the lifting block is fixedly connected to a movable rod, and a rectangular groove is provided on the left side of the frame. The pneumatic spot welding machine, by setting a protective mechanism, during the spot welding process using the spot welding machine body, the motor drives the threaded rod to rotate clockwise or counterclockwise, so that the lifting block drives the protective plate to move upward or downward to a suitable position, and then the handle is pulled forward to move the protective plate close to the operator's eyes, so as to avoid arc damage to the eyes.

[0004] However, the existing spot welding machines are large in size and require external mobile machines to be moved, which makes the movement time-consuming, labor-intensive and inconvenient; therefore, it does not meet the existing needs. In this regard, we propose a spot welding machine that is easy to move. Utility Model Content
