Miller 800 Duo Pro Welder/Generator

This Deutz diesel welder/generator is built for two welders at once: it delivers 800 amps of DC output to a single arc, or splits to 400 amps between two separate operators working off the same machine. ArcReach remote control and a vandalism lockout kit are included, which fits crews running shared equipment on an open site. Why the dual-arc rating matters Duty cycle is rated 100 percent at 400 amps with two operators and 100 percent at the full 800-amp single-operator output, so neither mode is limited to intermittent use. Multi-arc capability means this is built specifically for that shared-machine setup rather than as an afterthought. Engine and build details A four-cylinder Deutz TD2.9 L4 diesel, turbocharged and Tier 4 compliant, carries a 25-gallon tank and a 120-volt block heater Expect as much as 27,000 peak watts from the generator on three-phase power, roughly 15,000 watts on single-phase Shipping weight is 1,869 pounds; confirm your lift and trailer capacity before ordering Rated Career Welder skill level, heavy industrial duty, new condition Miller builds this model to order, quoting roughly 2 to 3 weeks for shipment, so factor that into your schedule. It ships with a 3-year manufacturer's warranty and the same control-panel conveniences as the rest of this engine family, including auto-remote sense at the 14-pin receptacle and a rust-resistant powder coat. Can two welders really work off one machine at the same time? Yes, the 400-amp two-operator duty cycle is rated at 100 percent, same as the single-operator 800-amp rating. Is this a vandalism-resistant machine? It includes a lockout panel, per the listed features.
