Miller Big Blue 400 (CAT) - 907774001
Designed with the professional in mind, the Big Blue 400 Pro is the best for ease of use, reliability and fuel economy.
Heavy-Duty Low-Speed CAT Industrial Diesel Engine
With the reliability you expect from Miller, the CAT C1.5T turbo-charged three-cylinder, liquid-cooled, industrial diesel engine is backed by world-class support and service through the global CAT dealer network.
Exclusive ArcReach technology uses existing weld cables to communicate process adjustment commands back to the engine-driven welder. With an ArcReach system, amperage voltage are conveniently located at the operator's fingertips — not back at the power source.
Unlike conventional DIG that provides a preset amount of short-clearing current, Miller’s proprietary Dynamic DIG works on a time-based algorithm that automatically adjusts the amount of current required to clear a short. What does this mean? A smoother more consistent arc that can be tailored to match application, material, fit-up, and welder technique.
Industrial USB PortQuickly upload the latest software and download machine log files to retrieve in-depth information such as diagnostics and machine statistics.
Advanced Features for the Professional Welder
Depending on polarity and which ArcReach accessory is connected, the system automatically detects and switches to the correct process - reducing the need to access the power source.
Control Panel Lock Out
While under control of an ArcReach accessory, process and amperage/voltage adjustments are locked out at the power source, preventing accidental changes by personnel other than the welding operator.
Increased Productivity & SafetyMore arc-on time, and reduced exposure to slip, trip, and fall hazards can be realized using ArcReach because less time is spent going back to the welding power supply to set process and arc amperage or voltage.
Other Standard Features
Digital preset weld meters, output contactor control, and automatic idle.
ArcReach Heater Compatibility
Take charge of your field preheat and bakeout applications up to 600 degrees Fahrenheit (315°C). This system uses induction heating to generate heat in workpieces, so welders can do their own preheating quickly and safely. A part of the ArcReach technology platform, the ArcReach Heater is an accessory for select ArcReach welding power sources.
