ARC-800 AT Arc Stud Welder

The ARC-800 AT is a transformer-based Drawn Arc and Short Cycle stud welder engineered for welding mild steel and stainless steel on materials approximately 0.08” (2 mm) thick and greater. Delivering welding currents up to 800 A, it supports studs from #4 to 1/2" (M3 to M12 ) and can be configured with automatic welding heads or an automatic stud feeder for production automation. Sunbelt Stud Welding supplies the ARC-800 AT throughout the United States from Houston, Texas.

FAQs

The Arc-800 AT is designed for welding studs on steel sections approximately 2 mm thick and above. It is commonly used for structural steel fabrication, heavy equipment, industrial manufacturing, and construction applications.

The ARC-800 AT is built for sheet metal about 2 mm and thicker, on mild steel and stainless steel. Thinner gauges are typically better suited to a Capacitor Discharge (CD) welder instead.

M3 to M12, dia. 2 to 10 mm, or #4 to 1/2", dia. 14 ga to 3/8", using drawn arc or short cycle stud welding.

400V, 3-phase, 50/60 Hz, with a 35A slow-blow fuse and 32A primary plug. Alternate primary voltages, including 230/460V and 575V, are available by order number.

Yes. It includes an integrated mains filter and galvanic separation between the transformer and control unit, designed for the voltage fluctuations common on construction sites.

PAH-1 hand guns, run manually or with the VBZ-3 automatic feeder, and the KAH 412 or KAH 412 LA automatic welding heads for hands-free operation.
