Miller Big Blue 500X Pro with ArcReach

The Miller Big Blue 500X Pro with ArcReach is a high-capacity, engine-driven welder designed for demanding applications in mining, process piping, heavy construction, and structural steel fabrication. With multi-process capabilities including Stick, TIG, MIG, and Air Carbon Arc Gouging (CAC-A), this powerful welder delivers up to 500 amps of welding output, ensuring superior performance on remote job sites.

Equipped with ArcReach® technology, the Big Blue 500X Pro minimizes downtime by enabling remote parameter adjustments, enhancing arc-on time and improving jobsite safety. The Auto Remote Sense™ feature detects if a remote control is connected, eliminating confusion between remote and panel operations.

Powered by a low-speed industrial diesel engine, this machine provides 15,000W of continuous auxiliary power (21,000W peak) to support tools like grinders, drills, and floodlights. Built with thermal overload protection, Lift-Arc TIG with Auto Crater and Auto Stop, and infinite arc control, the Big Blue 500X Pro ensures efficient operation and easy handling of tough-to-weld materials.

The powder-coated frame with zinc-rich primer provides resistance to rust and corrosion, extending the machine’s life in harsh conditions. Maintenance is made easy with features like remote oil drain and industrial USB ports for diagnostics and software updates.
