The Big Blue 450 Duo CST, a dual-operator diesel engine-driven welding generator, features two CST 280 Stick/TIG inverters and 12,000 watts of continuous three-phase power in a single unit. The generator is powered by a Mitsubishi S4L2 4-cylinder diesel engine and provides increased productivity by allowing two welders to use the same machine through 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 10 dBa quieter than other models, according to Miller Electric Mfg. Co. Furthermore, built-in thermal overload protection prevents machine damage if the duty cycle is exceeded or if airflow is blocked. The engine is designed to run more than 10,000 hours before its first major overhaul, and the Big Blue 450 Duo CST offers an easy-to-understand meter maintenance display. There is also a low fuel shutdown that shuts down the system before it runs out of fuel, making restarts easy.
