The new Big Blue 400 Pro diesel-engine welder/generator from Miller is more efficient and powerful than ever, with 400-amp output now available in a 300-amp package.
The reliable low-speed diesel machine offers multi-process flexibility and versatility to work on multiple jobs, with a focus on ease of use, reliability and fuel economy. Improved weld control increases arc quality and optimizes welding output.
“Miller has redesigned its diesel engine-driven welder/generators to maximize power output and fuel efficiency,” said Joe Gitter, industrial engine drive product manager for Miller Electric Mfg. Co. “The result is a full product lineup of exceptionally powerful and robust diesel engine-driven welder/generators.”
The new machine provides 400 amps of output at 100 percent duty cycle. The 12 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 Big Blue 400 Pro can handle most jobs with ease, including gouging with up to 1/4-inch carbons.
Designed to operate more than 10,000 hours before the first basic overhaul, the clean, efficient engine offers quiet operation of just 66.5 dB at idle and 72.1 dB at maximum output, improving jobsite communication and safety. There are multiple EPA-compliant engine choices available (Caterpillar, Kubota and Mitsubishi).
