Capacitive Energy Storage Spot Welding Machine

The Capacitive Energy Storage Spot Welding Machine uses power-frequency AC, which is rectified by a rectifier and then charged into a capacitor. The stored energy is discharged through a welding transformer, converting it into low-voltage, concentrated, stable pulse current. The resistance heat generated at the contact points of the welded workpieces melts the metal for welding.
