Miller Big Blue 500 Pro (Kubota)

Clean, quiet, Multiprocess machine delivers up to 500 amps of welding power with an EPA Tier 4 Final engine, ideal for heavy use.


  • Heavy-Duty Low-Speed Kubota V2403 Industrial Diesel Engine: The cleanest, greenest diesel power available. Kubota T4F models utilize diesel oxidation catalyst (DOC) technology to keep the air clean with NO exhaust after-treatment maintenance.
  • Quiet Operation: Improves work site safety and communication.
  • 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.
  • Industrial USB Port: Quickly upload the latest software and download machine log files to retrive in-depth information such as diagnostics and machine statistics.
  • 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).
  • 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.
  • Not Included:
    • Weld Leads
