The Pro-Weld International

ARC-800 is a compact and portable stud welding power supply capable of welding
studs thru 1/2″ diameter weld base. The fully regulated power supply, which operates on
single-phase power, produces a smooth, stable welding arc. Both the weld time and weld
current are infinitely adjustable for preciseness and repeatability.

For maximum flexibility, the weld time can be switched between two ranges.
The expanded short 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.
