Miller® Big Blue® 800 Duo Pro Series Engine Driven Welder #907587

A complete multi-process & multi-operator welder/generator that delivers two independent pipe quality arcs in one complete package. Upgrade to the SF model to unlock advanced RMD® & Pulsed MIG processes with the FieldPro™ Smart Feeder.

Multi-Arc Welding

One dependable engine—two independent arcs with up to 400 amps each. Or plug in additional inverters for a true multi-operator work platform! Example: Two additional XMTs equals four operators, up to 200 amps each. Premium-quality arcs allow operators to work independently with no arc interaction. Multi-operator welding has never been easier or more versatile.

Electronic Engine Display

Simultaneously displays fuel level, engine hours, coolant temperature, oil pressure, battery volts, and engine RPM. Also tracks oil change intervals and displays engine diagnostics for quick and easy servicing.

Infinite Arc Control

Allows the arc characteristics to be changed for specific applications in Stick, TIG, MIG and FCAW.

Low OCV Stick (VRD)

Reduces the open-circuit voltage to 15 volts when the welding power source is not in use. This feature increases operator safety without compromising arc starts.

FieldPro™ Smart Feeder Compatible (SF Model Only)

Advanced RMD & Pulsed MIG processes are now available in an engine-driven welder/generator. Discover increased productivity, quality, and improved efficiency in field welding with the new Big Blue 800 Duo Pro SF with FieldPro Smart Feeder.

Heavy-Duty DEUTZ TD2.9 L4 Tier 4 Final Engine

The cleanest, greenest diesel power available. Utilizes Diesel Oxidation Catalyst (DOC) technology to keep the air clean with NO exhaust after treatment maintenance.

Increased Efficiency

More arcs and better fuel economy equal increased profits for your business. Estimated savings are 34 percent with a dual-operator unit versus two single-operator units.

Standard Features

All models include digital preset weld meters, automatic idle, 120V block heater, and vandalism lockout (protects control panel and receptacles).
