Miller Big Blue 400 Pro Mitsubishi Welder/Generator (907733)
The Miller Big Blue 400 Pro (907733) is a Mitsubishi-powered engine-drive welder generator for stick, MIG, flux-cored and TIG welding. Its generator delivers 12,000 watts peak and 10,000 watts continuous, and weld output is rated at a 60% duty cycle at 300 A.
MIG/FCAW output runs from 14 to 40 V with DC polarity, and the machine is rated for heavy industrial work on mild and stainless steel. It measures 32 in high, 26.25 in wide and 56 in long, with sound levels of 68.7 dB at idle and 72.1 dB while welding.
Digital meters with SunVision technology and simple-to-set controls sit alongside an industrial USB port, adjustable hot start and a standard 14-pin receptacle. Automatic engine idle, a 120V block heater, low OCV stick, thermal overload protection and an HD powder coat against rust and corrosion are standard.
