Capacitance Energy Storage Spot Welder, charge first & then welding discharge during welding, the energy stored in the capacitor and releases on the welding transformer instantly to generate higher current. Power Saving because of small capacity power source required, reducing cost, unaffected by power voltage drop, suitable for welding of the low-impedance metal keep materials such as aluminum, brass, nickel alloy, copper wire, silver tipped contact and capacitor.
