The Big Blue 450 Duo CST, a dual-operator, diesel engine-driven welding generator with two CST 280 Stick/TIG inverters from Miller Electric, offers 12,000 watts of continuous three-phase power in a single unit. Powered by Mitsubishi’s S4L2 four-cylinder diesel engine, the unit allows two welders to work off the same machine with two separate welding outputs. The Tier-4-interim-compliant machine operates at a low 1,800 rpm, reducing fuel use and lower noise, and features a process-selector for Stick and TIG applications. www.millerwelds.com/
