Description
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.
Dynamic DIG™
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.
Advanced Features for the Professional Welder
Adaptive Hot Start makes starting stick electrodes easy without creating an inclusion.
Infinite arc control available in the Stick and Wire modes for easier fine tuning of tough-to-weld materials and out-of-position applications.
