Base model with 240-volt 3-phase power, ArcReach® and vandalism lockout kit

The most powerful T4F diesel welder/generator/air compressor in the industry. The Big Blue 800 Duo Air Pak offers robust output for welding and power generation, and is ideal for dual-operator applications on labor intensive jobsites, or jobsites with limited space.

Features

• The cleanest, greenest diesel power available. Utilizes Diesel Oxidation Catalyst (DOC) technology to keep the air clean with NO exhaust after treatment maintenance.
• Get full control of your machine in the palm of your hand, from wherever you are on the jobsite, so you can work hassle free. With wireless interface control, you can:
• Change welding processes
• Adjust parameters
• Select and save preset programs
• Turn the machine on/off
• View service reminders
• Extend time between fill ups and maintenance intervals while eliminating the need to go back to your machine to make adjustments.
• One dependable engine—two independent arcs with up to 400 amps each. Or plug in additional inverters for a true multioperator 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. Multioperator welding has never been easier or more versatile.
• ArcReach technology uses existing weld cables to communicate process adjustment commands back to the welder generator. With an ArcReach system, amperage & voltage are conveniently located at the operator’s fingertips – not back at the power source.
• All models include digital preset weld meters, automatic idle, 120V block heater, and vandalism lockout (protects control panel and receptacles).
• Unlike conventional DIG that provides a preset amount of short-clearing current, Miller’s proprietary Dynamic DIG works on a time-based algorithm that automatically adjusts the amount of current required to clear a short. What does this mean? A smoother more consistent arc that can be tailored to match application, material, fit-up, and welder technique.
• Quickly upload the latest software and download machine log files to retrieve in-depth information such as diagnostics and machine statistics.
• 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.
• 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. You’ll save even more with Wireless Interface Control. When your welder/generator is far away, it’s time-consuming to walk back to turn it off, so it ends up running all day. Use Wireless Interface Control to instantly turn your machine off when needed, saving fuel and money.
• 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.
• Take charge of your field preheat and bakeout applications up to 600 degrees Fahrenheit (315°C). This system uses induction heating to generate heat in workpieces, so welders can do their own preheating quickly and safely. A part of the ArcReach technology platform, the ArcReach Heater is an accessory for select ArcReach welding power sources.
