Description

The Big Blue 450 Duo CST is a rugged, compact, fuel-efficient diesel welder/generator that provides 2 superior arcs in one economical package.

  • Superior Stick arc performance even on the difficult-to-run electrodes like E6010.
  • 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.
  • Remote amperage control provided through 14-pin receptacle on front of the machine. This permits use of standard remote amperage control devices.
  • Mitsubishi S4L2 diesel engine. Used in industrial applications around the world, the S4L2 is designed to run 10,000 hours before major overhaul.
  • 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.

  • Quiet operation. In weld mode with 71.5 dBa at 23 ft (7 m), it up to 10 dBa quieter than competitive models, improving work site communication and safety.
    • 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.
