1770046 - Miller MDX-250 EZ-Select MIG Gun 15ft AccuLock S

Weld Smarter, Not Harder

Stop walking back and forth to your machine every time you need to change settings. The Miller® MDX-250 EZ-Select™ MIG Gun puts the power of the Millermatic® 255 directly in your hand. With the innovative EZ-Select™ trigger, you can toggle between up to four different weld programs just by tapping the gun trigger. Bright LED lights on the handle let you know exactly which program you are running, so you can switch from a root pass setting to a fill pass setting without ever lifting your hood or leaving the weld joint. This 15-foot gun is designed to keep you welding, not walking.

Superior Comfort and Feeding

Welding fatigue is real, but the MDX-250 is built to fight it. The handle features a comfortable rubber grip that stays secure in your hand, and the rear swivel keeps the heavy cable from dragging your wrist down as you maneuver around your workpiece. Beyond comfort, this gun delivers frustration-free wire feeding thanks to the AccuLock™ S consumables. The liner loads from the front and locks in place, ensuring the wire has a smooth, straight path to the contact tip. This means fewer burnbacks, less erratic arcs, and no more guessing if you trimmed the liner correctly. Whether you are welding mild steel or aluminum, the MDX-250 EZ-Select delivers the consistent performance you expect from Miller.

Built for the Pro

Rated at 250 amps at a 100% duty cycle with CO2, this gun is ready for heavy-duty work. It comes set up for .035 to .045 wire, making it perfect for structural work, fabrication, and manufacturing. If you own a Millermatic 255 or Multimatic 255, upgrading to the EZ-Select gun is the single best way to unlock the full potential of your machine and speed up your workflow.
