    Quickly upload the latest software and download machine log files to retrieve in-depth information such as diagnostics and machine statistics.

    Auto Remote Sense™ (ARS)

    Detects if remote control is plugged into the 14-pin receptacle and eliminates the 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).

    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.

    Manufacturer Reviews

    By: Andrew
    I'm a 798 Pipeliner. I have always been a die hard Lincoln man. It was time for me to purchase a new machine. I tested out side by side the same day the Lincoln SAE 300 Mp, MP Classic & the Miller Big Blue 400. I have just put the Big Blue 400 Pro on my welding rig. The Miller offered so much more control on the settings then the Lincoln. The price value for what the Miller offered compared to the Lincoln was much better. And the new Wireless Interface remote system is outstanding. With this remote you can adjust any setting on the fly from the ditch that you could do standing in front of the machine. I made fun & insulted my friends (in a friendly manner) when they bought their Miller's. Now it's their turn, they are killing me:)
