Proweld ARC 656

The ARC-656 is a compact lightweight stud welding power supply capable of welding studs thru 1/2” diameter reduced weld base. The power supply which operates on three phase power produces a smooth, stable welding arc. The front panel digital display indicates the weld time which is infinitely adjustable for preciseness and repeatability. The expanded time range provides fine adjustment of weld time for special short cycle applications such as welding to thin material. A specially designed electronic gun control circuit has been incorporated to increase overall reliability. If a fault condition occurs due to a shorted gun solenoid or a faulty control cable, the circuit will prevent gun retriggering and eliminate damage to printed circuit boards.
