Miller Big Blue 600 Pro Diesel Welder Generator, Kubota, 600A, 20,000W, 907737
The Miller Big Blue 600 Pro is a Kubota diesel welder generator delivering 600 A of DC welding output. Its generator produces 27,000 W peak on three-phase or 15,000 W on single-phase, with 20,000 W of continuous three-phase power, and an electronic engine display keeps fuel, engine data and service intervals in view.
The Kubota T4i diesel uses diesel oxidation catalyst technology, so the exhaust needs no aftertreatment maintenance. The electronic engine display shows engine RPM, battery voltage, oil pressure, coolant temperature, engine hours and fuel level at once, tracks oil change intervals and reports engine diagnostics.
This engine-driven welder has digital meters with SunVision Technology, an industrial USB port and a standard 14-pin receptacle that offers auto-remote sense, plus adjustable hot start, output control and auto-idle. An HD powder coat resists rust and corrosion, and a polarity reversing switch is reserved for Deluxe models.
