Miller Big Blue 450 Duo CST (Mitsubishi) 907477

The Big Blue 450 Duo CST is a durable, compact, fuel-efficient diesel welder/generator. The 450 can provide two simultaneous arcs while remaining economical and effective for operators. 

Big Blue 450 Duo CST Features:

Multi-function Fuel Gauge - Clear fuel level, engine hours, and customizable oil change reminders. The engine has an automatic shut down feature to prevent further damage in the case of high coolant temperature, low oil pressure, or low fuel level.

Heavy-Duty Low-Speed Mitsubishi S4L2 Industrial Diesel Engine - The Mitsubishi S4L2 is designed to run for 10,000 hours before any major overhaul is necessary. Backed by worldwide and world-class support and service.

Adaptive Hot Start™ For Stick Arc Starts - Automatically increases the output of a weld should the start require it.  Prevents the electrode from sticking and creating an inclusion.

Superior Stick Arc Performance - Even on difficult-to-run electrodes like E6010

Remote Amperage Control - Provided through a 14-pin receptacle in front of the machine.  This permits the use of standard and wireless remote amperage control devices.

Quiet Operation - At just 72.2 decibels at 23 feet (7 m), it's quieter than the vast majority of other single-operator models, improving job site communication and safety.

High Efficiency - Three-Phase, rotating-field generator requires less fuel and horsepower to operate.

Vandalism Lockout Kit -  Lockable hinged steel panel protects front control panels and ignition switch.
