Miller Big Blue 800 Duo Pro Diesel Welder Generator, 800A, 2 Operators, ArcReach

The Miller Big Blue 800 Duo Pro diesel welder generator delivers 800 A of DC welding output, or 400 A between two separate operators, from a Deutz engine. ArcReach technology, multi-arc welding capability and a vandalism lockout kit come with this model, and its generator produces 27,000 W peak on three-phase or 15,000 W on single-phase.

The Deutz TD2.9 L4 diesel is Tier 4 compliant, four-cylinder and turbocharged, with a 25-gallon fuel capacity and a 120 V block heater. 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. Continuous three-phase output is 20,000 W.

Paired with an ArcReach-compatible device, this engine-driven welder gives cordless remote control of the power source and lets weld settings be changed at the feeder, doing away with control cords and their cost. A vandalism lockout panel, digital meters with SunVision Technology, a 14-pin receptacle with auto-remote sense, an industrial USB port and an HD powder coat finish complete the welder/generator.
