Percussion and capacitive discharge welding systems use this type of power supply to deliver controlled energy pulses for joining small metal components, contacts, and terminals.

This Duffers Associates 311021 Percussion Welder Power Supply has been inspected and appears to be in good used condition overall. The top and sides of the enclosure show visible scratches, scuffs, and surface marks consistent with years of shop use — notably paint wear and light scoring across the top panel. The acrylic rack ears appear intact. The rear IEC inlet and front panel controls look complete and undamaged as shown in the photos. The model label on the rear reads clearly: Mod. No. 311021, Ser. No. 311. This unit has not been powered up or tested at our facility, but it was pulled from a working environment where it was previously in use.
