Miller Big Blue® 450 Duo CST Mitsubishi 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 282 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.

  • Stick Welding (SMAW)
  • DC TIG Welding (GTAW) Lift Arc

  • Heavy Construction
  • Structural Steel Work
  • Maintenance and Repair
  • Process Plant Piping
  • Sheet Metal

  • Superior arc quality. Proven CST 282 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.
