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

Features

  • Used in industrial applications around the world, the S4L2 is designed to run 10,000 hours before major overhaul. Backed by worldwide support and service.
  • Lockable hinged steel panel protects front control panels and ignition switch.
  • At just 72.2 decibels at 23 feet (7 m), it's quieter than most single-operator models, improving jobsite communication and safety.
  • Even on the difficult-to-run electrodes like E6010
  • Three-Phase, rotating-field auxiliary power unit requires less fuel and horsepower to operate.
  • Automatically increases the output of a weld should the start require it. Prevents the electrode from sticking and creating an inclusion.
  • Displays fuel level and engine hours, and can be customized to set oil change interval reminders. In the case of high coolant temperature, low oil pressure, or low fuel level, the engine will shut down to prevent damage, or make restarting easier.
  • Provided through 14-pin receptacle on front of the machine. This permits use of standard and wireless remote amperage control devices.
