OVERVIEW

Maximize Your Millermatic 255 with the MDX-250 EZ-Select

Take full command of your welding projects with the Miller® MDX-250 EZ-Select™ MIG Gun, a 15-foot torch designed to be the perfect partner for your Millermatic® 255 or Multimatic™ 255 welder. The standout feature of this gun is the EZ-Select™ trigger, which puts the power of your machine right in your hand. Instead of stopping work to adjust settings at the machine, you can cycle through up to four saved weld programs using the gun trigger. Bright LED lights on the handle let you know exactly which program is active, allowing you to switch from tacking to full welding or change settings for different metal thicknesses instantly. This seamless control saves time and keeps your focus where it belongs—on the arc.

Built for Comfort and Durability

Welding all day requires equipment that won't wear you out. The MDX-250 features a newly designed handle with a comfortable rubber grip that prevents slipping and absorbs vibration. The addition of a rear ball-and-socket swivel allows the heavy-duty cable to move freely, reducing the drag and weight on your wrist as you maneuver around corners or into tight spaces. Rated for 250 amps, this air-cooled gun is built to handle tough jobs, delivering a 100% duty cycle with CO2 gas. Whether you are in automotive repair, heavy fabrication, or manufacturing, this gun delivers the reliability Miller is known for.

Flawless Feeding with AccuLock Technology

Frustrated by burn-backs and bird-nesting? The MDX-250 comes equipped with AccuLock™ MDX consumables, a system engineered to keep your wire feeding smoothly. The contact tips lock into the diffuser with a taper fit, creating a solid electrical connection that keeps the tip cooler and extends its life. The liner is centered perfectly with the tip, ensuring the wire has a straight shot to the weld pool. This is especially important for Pulsed MIG welding, where consistent arc length is key. The gun arrives ready to run .030 to .035 wire, making it a versatile choice for standard steel and stainless steel applications.
