Miller® Big Blue® 400 Pro (CAT)

Designed with the professional in mind, the Big Blue 400 Pro is the best for ease of use, reliability and fuel economy.

NEW 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. Industrial USB Port: Quickly upload the latest software and download machine log files to retrieve in-depth information such as diagnostics and machine statistics. Superior Arc Performance: Four preset DIG settings: (Stick) Hot Start™ (Stick) Lift-Arc™ TIG with Auto-Stop™ Crater-out MIG/FCAW arc performance Quiet Operation: Improves work site safety and communication. Simple-to-Set Controls: Requires no elaborate procedure - just select process and weld! Auto Remote Sense™ (ARS): Detects if a remote control is plugged into the 14-pin receptacle and eliminates confusion of a remote/panel switch. Thermal Overload Protection: Prevents machine damage if the duty cycle is exceeded or airflow is blocked. Meter Maintenance Displays: Fuel gauge Hour meter function Oil change interval High coolant temperature and low oil pressure shutdowns Low fuel shutdown - engine shuts down before system runs out of fuel, making restarts easy. Other Standard Features: Digital preset weld meters, output contactor control, and automatic idle.
