Miller Electric Big Blue 600 Pro Welder/Generator Goes Tier 4-Final, Gains Power

The Big Blue 600 Pro welder/generator replaces the Tier 4-Interim Big Blue 500 with a more powerful Tier 4-Final–compliant engine.

Designed for the U.S. market, this 600-amp machine is designed for jobs that require high output for welding, gouging and auxiliary power. It is powered by a Kubota’s V2403 turbocharged four-cylinder industrial liquid-cooled engine rated at 48.9 horsepower. The unit provides several key upgrades from the previous model including improved arc characteristics, digital weld meters and display, and three-phase power available anytime—even while welding—Miller says. All models include a 4-inch electronic engine display, which replaces the traditional cluster of analog gauges.
