The Big Blue 800 Duo Air Pak and Big Blue 800 Duo Pro diesel-engine welder/generators from Miller offer dual operation capabilities. A 33 percent increase in rated power output results in 27,000 watts of generator power and up to 800 amps of weld power for a single operator, or 400 amps each for two weld operators. Additional inverters can be plugged into the machines to create a multi-operator work platform, with operators able to weld and get three-phase power at the same time. The multiprocess machines provide improved weld control that increases arc quality and optimizes welding output, resulting in better welds on thicker material, Miller says. New Tier 4-Final engines reduce emissions. In addition to fuel savings on a per-arc basis, the dual-operator feature also saves space on the work truck and jobsite, with lower maintenance costs compared to two separate machines.
