The Pro-Weld International

ARC-1850 is a compact and portable stud welding power supply capable of welding studs thru 7/8″ diameter weld base. The power supply which operates on three phase power has the added feature og weld current regulation that improves stud welding consistency. Both the weld time and weld current are infinitely adjustable for preciseness and repeatability.

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.
