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.
Heavy-Duty Low-Speed DEUTZ TD2.9 L4 T4F Industrial Diesel Engine
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.
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 a true multi-operator (3+ arc) work platform!
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.
Advanced Features for the Professional Welder
• 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.
