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

The Miller Big Blue 400 Pro is a multiprocess welder generator with a Mitsubishi engine, covering stick, MIG, flux-cored, DC TIG and air carbon arc work. It supplies 20-400 A of DC stick and TIG output, a 14-40 V range for MIG and flux-cored welding, and 12,000 W peak or 10,000 W continuous generator power.

This engine-driven welder pairs simple-to-set controls with digital meters using SunVision Technology, an adjustable hot start and an industrial USB port. Low OCV stick operation, thermal overload protection and a standard 14-pin receptacle are built in, and automatic engine idle and a 120 V block heater look after the Mitsubishi engine. The HD powder coat finish resists rust and corrosion.

The Mitsubishi-engine Big Blue 400 Pro weighs 993 lbs and measures 32 in. high, 26.25 in. wide and 56 in. long. As a welder/generator it delivers 12,000 W at peak and 10,000 W continuously, and its process range spans stick (SMAW), MIG (GMAW), flux-cored welding (FCAW), DC TIG (GTAW) and air carbon arc gouging.
