What is a spot welder

Spot welding machine is a kind of mechanical equipment. It adopts the principle of double-sided double-point overcurrent welding. When working, two electrodes press the workpiece so that the two layers of metal form a certain contact resistance under the pressure of the two electrodes. When the electrode flows through the other electrode, an instant thermal fusion is formed at the two contact resistance points, and the welding current flows from the other electrode along the two workpieces to this electrode to form a loop instantly, and the internal structure of the workpiece to be welded will not be damaged.
