1, the current is small to 50KW, large to 200KW. The voltage varies from 5V to 11V.

2. The spot welding machine adopts the principle of double-sided double-point over-current welding. When working, the two electrodes pressurize the workpiece so that the two layers of metal form a certain contact resistance under the pressure of the two electrodes. When the welding current flows from one electrode to the other electrode, an instantaneous thermal 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.
