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 of 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.
