Dual-operator welding generator

Designed for use in construction, maintenance, pipe welding and general fabrication, the Big Blue 450 Duo CST is a dual-operator, diesel engine-driven welding generator that features two CST 280 Stick/TIG inverters and 12,000 watts of continuous three-phase power in a single unit. Powered by Mitsubishi’s S4L2 4-cylinder diesel engine, the Big Blue 450 Duo CST provides increased productivity by allowing two welders to work off the same machine with two separate welding outputs. The Tier 4i-compliant machine operates at a low 1,800 rpm, which reduces fuel use and keeps noise levels up to 10dBa quieter than other models. www.millerwelds.com/
