The Professional Welder’s Choice — designed with the professional in mind, the Arc Stud series has the best welding arc in their class!

Wind Tunnel Technology ™ protects electrical components and

PC boards from contamination.

Fan-On-Demand ™ cooling system operates only when needed, reducing noise, energy use and the amount of contaminants pulled through machine.

Ultra-tough, polycarbonate-blended

cover for control panel protects front controls from damage.

Inverter arc control technology provides greater current control for superior Arc Stud performance.

Auto-Link ® circuit automatically links the power source to primary voltage being applied (460/575 VAC, three-phase).

International-style weld disconnects provide high-quality weld cable connections.

NEW! Brushed aluminum case is the professional’s choice.

Lightweight, aerospace-grade aluminum offers protection with the benefit of reduced weight.

Line voltage compensation keeps power constant even if power input varies by ±10%.

Large, dual digital meters are easy to view and are presettable to ease setting weld output.

Process select button reduces the number of control setup combinations without reducing any features.

Standard 4-pin receptacle allows for simple connection of

Arc Stud application gun.

Power source and stud application gun are warranted for 1 year, parts and labor.
