Miller Big Blue® 450 Duo CST Diesel Welder 907477
The Miller Big Blue® 450 Duo CST combines the robust frame of a Miller diesel welder with the proven welding arc quality of Miller's CST 280 stick welder. The result is a rugged, compact, fuel-efficient diesel welder/generator that provides 2 superior arcs in one economical package. The Big Blue 450 Duo CST also produces 12,000 watts of 3-phase, 240 volt auxiliary generator power and 10,000 watts of single phase 120/240 volt generator power.Processes

Superior arc quality. Proven CST 280 Stick/TIG welding performance maximizes productivity and minimizes rework. The process selector knob automatically sets the proper dig setting on difficult Stick electrodes, like E6010, for superior performance.
Dual operation. The Big Blue 450 Duo CST has two separate outputs powered by one low-speed diesel engine, so two operators can use it at the same time for increased efficiency and productivity.
Efficient design. With two standard CST 280s conveniently packaged in one compact case, the fuel-efficient Big Blue 450 Duo CST is the right size and weight for your operation.
Quiet operation - At just 72 dB at full load and 71.3 dB at no load, the Big Blue 450 Duo CST produces less noise, resulting in easier communication and a safer jobsite.
Exceptional fuel efficiency. Less fuel is required to operate, resulting in fuel savings of up to 35 percent. The more you use it, the more you save.
Easy to use. Simple interface eliminates guesswork and decreases training time. With minimum switch selections to set, you get maximum control and performance.
Tier 4F compliant. Ecologically friendly welder/ generator runs clean, meeting strict Tier 4F requirements and minimizing your impact on the environment.
Renowned reliability. Every component is engineered and built for ultimate reliability, resulting in less downtime and more productivity.
Built tough. Miller rates the Big Blue 450 Duo CST output at 122° F/50° C to ensure top performance in the most extreme conditions.
Mitsubishi S4L2 diesel engine. Used in industrial applications around the world, the S4L2 is designed to run 10,000 hours before major overhaul.
Wireless hand remote control compatible. This industry exclusive allows you to extend your remote welding control range to 300 feet for jobsite mobility and operator safety.
Adaptive Hot Start™ for Stick arc
starts automatically increases the output amperage at the start of a weld should the start require it. Prevents the electrode from sticking and creating an inclusion.
Lift-Arc™ start provides TIG arc starting without the use of high frequency.
Meter maintenance displays:
Hour meter function
Oil change interval
High coolant temperature and low oil pressure shutdowns
Low fuel shutdown - engine shuts down before system runs out of fuel, making restarts easy.
Thermal overload protection prevents
machine damage if the duty cycle is
exceeded or airflow is blocked.
High efficiency. 3-phase, rotating-field
generator requires less fuel and
horsepower to operate.
