Miller Big Blue 400 Pro ArcReach Welder Generator, Mitsubishi, 10,000W

The Miller Big Blue 400 Pro ArcReach multiprocess welder generator pairs a Mitsubishi engine with ArcReach cable length compensation and no control cords. It covers stick, MIG, flux-cored, DC TIG and air carbon arc work with 20-400 A of DC stick and TIG output, and the generator supplies 12,000 W peak and 10,000 W continuous power.

ArcReach brings cable length compensation (CLC), removes the need for costly control cords and, per Miller, improves jobsite safety, gives the operator more control and keeps the machine compatible with a fleet of ArcReach power sources. MIG and flux-cored welding run over a 14-40 V range, and the 993 lb engine-driven welder measures 32 in. high, 26.25 in. wide and 56 in. long.

Simple-to-set controls, digital meters with SunVision Technology, an industrial USB port and adjustable hot start handle setup, while low OCV stick operation, thermal overload protection and a standard 14-pin receptacle round out the panel. Automatic engine idle and a 120 V block heater serve the Mitsubishi engine, and the welder/generator wears an HD powder coat that resists rust and corrosion.
