Miller Big Blue® 400 Pro Engine-Driven Welder #3907774001

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

Features:

NEW Heavy-Duty Low-Speed CAT Industrial Diesel Engine

  • With the reliability you expect from Miller, the CAT C1.5T turbocharged three-cylinder, liquid-cooled, industrial diesel engine is backed by world-class support and service through the global CAT dealer network.

ArcReach® Technology

  • Exclusive ArcReach technology uses existing weld cables to communicate process adjustment commands back to the welder generator. With an ArcReach system, amperage & voltage are conveniently located at the operator's fingertips — not back at the power source.

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.

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.

Auto-Process Select™

  • 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.

Fleet Compatibility

  • Cross-Platform Compatible. The same ArcReach accessories that work on engine-driven equipment can also be used on select ArcReach-equipped XMT®, Dimension™, and PipeWorx 350 FieldPro™ power sources.
  • Reverse Compatible. ArcReach-equipped power sources work with non-ArcReach accessories; however, the complete ArcReach benefit is only realized with the ArcReach system.

Increased Productivity & Safety

  • More 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.

Manufacturer Reviews

Michael
I don't have many hours on this machine yet. But it's quiet, great stable arc, and fuel efficient. The controls work great. Mainly used for pipe welding and around the property
Chantz
I typically use my machine on all types of metal mainly pipeline construction. It welds great and has so many options to use. Has great generator power as well to use on farm repair projects.
Rob
Purchased this for American Welding Academy welding school. We are using this to give students a "real " feel of what it is like welding on an engine driven machine. They love it. This is a sweet machine that can be dialed in for just about any job. Love Miller and Big Blue!!
