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.

Lorem Ipsum has been the industry’s standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.
