Capacitance Energy Storage Spot Welder, charge & discharge welding, the energy stored in the capacitor releases on the welding transformer instantly to produce high current. Saving electricity, small required power capacity, reducing cost, unaffected by powervoltage drop, suitable for the welding of low-impedance materials such as aluminum, brass, nickel alloy, copper wire, silver tipped contact and capacitor.

A short full discharge time of 0.003 second with a small consumption of electrode and a stable welding quality.
