The Miller Big Blue 800 Duo Pro is the most powerful Diesel welder/generator in the industry. Offers robust output for welding and power generation. Ideal for applications with intense needs or limited space. Equipped with ArcReach technology, operators can change weld settings from the ArcReach feeder remote.

T4F Compliant 

The heavy-duty Low-Speed DUETZ TD2.9 L4 T4F Industrial Diesel Engine is the cleanest, greenest diesel power available. DUETZ T4F models utilize diesel oxidation catalyst (DOC) technology to keep the air clean.

Multi-Arc Welding

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 true multi-operator (3+ arc) work platform.

Increased Efficiency 

More arc and better fuel economy equal increased profits for your business. Estimated savings are 34% with a dual-operator unit compared to two single-operator units. 

Advanced Features for the Professional Welder
  • Adaptive Hot Start makes starting stick electrodes easy 
  • Infinite arc control available in the stick and wire modes for easier fine tuning on unique applications
  • Lift-Arc TIG provides arc starting that minimizes the risk of electrode /work contamination without the need for high frequency
Dynamic DIG

Miller's proprietary technology works on a time-based algorithm that automatically adjusts the amount of current required to clear a short. Basically that means a smoother, more consistent arc that can be tailored to match application, material, fit up, and welder technique.

ArcReach Technology 

Exclusive technology uses existing weld cables to communicate process adjustment commands back to the welders generator. With an ArcReach system, amperage and voltage are at the operator's fingertips without having to be at the power source. 

Increased Productivity & Safety

More arc-on time, and reduced exposure to slip, trip and fall hazards by having fewer trips back to the power source.

Electronic Engine Display 

Simultaneously display of 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. 

Other Standard Features

Output contactor control, digital meters with SunVision automatic idle, thermal overload protection, and 120-volt engine block heater. Includes industrial USB port to upload the latest software and download machine log files for diagnostics.
