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 materials.
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.
