Miller Electric, 907751, Engine Driven Welder, 800 A Max Welding Amperage, Diesel, Dual Outputs, ArcReach Technology

The most powerful T4F diesel engine-driven welder in the industry. The Big Blue 800 Duo Pro offers robust output for welding and auxiliary power output, and is ideal for dual-operator applications on labor intensive jobsites, or jobsites with limited space. Equipped with ArcReach® technology, operators can change weld settings from the ArcReach feeder or remote. RMD® & Pulsed MIG welding capabilities are added with the ArcReach Smart Feeder.

Does Not Include

• Weld leads

Features

• 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.
• Electronic engine display simultaneously displays fuel level, engine hours, coolant temperature, oil pressure, battery volts, and engine RPMs. Also tracks oil change intervals and displays engine diagnostics for quick and easy servicing.
• Quickly upload the latest software and download machine log files to retrieve in-depth information such as diagnostics and machine statistics.
• One dependable engine - two independent arcs with up to 400 amps each (or 800 amps for a single operator). Plug in additional inverter welders for a true multi-operator (3+ arc) work platform!
• 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.
• More arc-on time, and reduced exposure to slip, trip, and fall hazards can be realized using ArcReach because less time is spent going back to the welding power supply to set process and arc amperage or voltage.
• Output contactor control, digital meters with SunVision™ automatic idle, thermal overload protection, and 120-volt engine block heater.
• ArcReach technology uses existing weld cables to communicate process adjustment commands back to the engine-driven welder. With an ArcReach system, amperage & voltage are conveniently located at the operator's fingertips - not back at the power source.
• 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.
• Adaptive Hot Start™ makes starting stick electrodes easy without creating an inclusion. Infinite arc control available in the Stick and Wire modes for easier fine tuning of tough-to-weld materials and out-of-position applications. Lift-Arc™ TIG provides arc starting that minimizes the risk of electrode/work contamination without the need for high frequency.
• The cleanest, greenest diesel power available. DEUTZ T4F models utilize diesel oxidation catalyst (DOC) technology to keep the air clean with NO exhaust after-treatment maintenance.
