Resistance Welder DC Capacitor Model NRW-DC150A

Resistance Welder DC Capacitor Model NRW-DC150A

The NRW-DC150A is a resistance welding machine providing direct current (DC) output via a capacitor discharge design.
The unit is typically used in combination with a hand-held or automated welding head for joining connecting semiconductor lead frames and capacitor hoop materials. The weld is made when energy stored in the large-capacity capacitor is instantly discharged to the welding head for welding.
