Miller Big Blue 450 Duo CST Diesel Welder / Generator
The Big Blue® 450 Duo CST is a rugged, compact, fuel efficient diesel welder/generator that provides 2 superior arcs in one economical package.
- Multi-function fuel gauge: 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 don to prevent damage or make restarting easier.
- 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.
- Remote Amperage Control: Provided through 14-pin receptacle on front of the machine, and permits use of standard and wireless remote amperage control devices.
