907733 - BIG BLUE 400 PRO (MITSUBISHI)

Miller® Big Blue® 400 Pro (Mitsubishi)

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 Mitsubishi S4L2 Industrial Diesel Engine: Used in industrial applications around the world, the S4L2 is designed to run 10,000 hours before major overhaul. Backed by worldwide support and service. 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. Industrial USB Port: Quickly upload the latest software and download machine log files to retrieve in-depth information such as diagnostics and machine statistics. Digital Meters with SunVision™: Enables welding parameters to be viewed with greater clarity at virtually any angle. Meters can be seen clearly even in direct sunlight. Auto Remote Sense™ (ARS): Detects if a remote control is plugged into the 14-pin receptacle and eliminates confusion of a remote/panel switch. Simple-to-Set Controls: Requires no elaborate procedure - just select process and weld. HD Powder Coat: All painted sheet metal is pretreated with a zinc-rich primer to provide extra protection against rust & corrosion (comparable to stainless steel). Quiet Operation: Improves work site safety and communication. 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. Lift-Arc™ TIG provides arc starting that minimizes the risk of electrode/work contamination without the need for high frequency. Low OCV Stick (VRD): When activated, reduces the open-circuit voltage to 15 volts when the power source is not in use, increasing operator safety without compromising arc starts. Other Standard Features: Output contactor control, automatic idle, thermal overload protection, and 120-volt engine block heater.
