Miller Electric Big Blue 400 Pro Diesel Welder/Generator

March 11, 2014

The Big Blue 400 Pro diesel-engine welder/generator from Miller has 400-amp output now available in a 300-amp package, the company says. The low-speed diesel machine offers multiprocess flexibility and versatility to work on multiple jobs. Improved weld control increases arc quality and optimizes welding output. The machine provides 400 amps of output at 100 percent duty cycle, and the12 kW peak auxiliary power or 10kW continuous auxiliary generator power available while welding allows for additional plug-in inverters for more versatile use as a multi-operator unit. The unit also can gouge with up to 1/4-inch carbons. Designed to operate more than 10,000 hours before the first basic overhaul, the engine offers operation of 66.5 dB at idle and 72.1 dB at maximum output. There are multiple EPA-compliant engine choices available (Caterpillar, Kubota and Mitsubishi).
