Spot welding machine technical parameters

DN1 spot welding machine uses double-sided double-point over-current welding principle, the work of the two electrodes pressurized workpiece so that the two layers of metal in the two electrodes under the pressure to form a certain contact resistance, and welding current from one electrode through another When the electrode forms an instantaneous thermal welding at the two contact resistance points, the welding current instantly flows from the other electrode to the electrode along the two workpieces to form a loop without damaging the internal structure of the workpiece to be welded.
