The most powerful lineup of diesel welder/generators in the industry.
All offer robust output for welding and power generation, and are ideal for dual-operator applications
on labor intensive jobsites, or jobsites with limited space.
More power. 800 amps of weld power and 27,000 watts of peak generator power.
Multi-arc welding. 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 XMT multiprocess machines 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.
Heavy-duty low-speed T4F and T4i industrial diesel engines. The cleanest, greenest diesel
power available. Utilizes diesel oxidation catalyst (DOC) technology in T4F models 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.                                  Big Blue® 800 Duo Pro. Multioperator work platform delivers two premium arcs (up to 400 amps each) allowing welding operators to work independently with no arc interaction.
Big Blue® 800 Duo Air Pak™ All-in-one welder/generator eliminates the need for an auxiliary air compressor. The industrial Ingersoll Rand screw-type air compressor is ideal for gouging and running pneumatic tools.
