OVERVIEW

Experience Superior Comfort with the Miller MDX-100 MIG Gun

The best welding gun is the one you never have to think about—it just works. The Miller MDX-100 MIG Gun (15 ft) is designed with exactly that philosophy in mind. If you are tired of fighting with stiff cables, uncomfortable handles, or inconsistent wire feeding, the MDX-100 is the upgrade your Millermatic or Multimatic welder deserves. This gun features an ergonomically sculpted handle with rubber overmolding that fits naturally in your hand, providing a secure grip that reduces fatigue during long welding projects. The addition of a rear ball-and-socket swivel allows the cable to move freely, preventing the wrist strain often caused by fighting a rigid torch cable.

Beyond comfort, the MDX-100 solves the most common frustration in MIG welding: wire feeding issues. Thanks to the revolutionary AccuLock MDX consumable system, the liner is automatically centered and locked without the need for measuring or set screws. This error-proof design guarantees a smooth path for your wire, eliminating the chatter and burnbacks that ruin contact tips and stall your progress. The contact tips themselves feature a tapered design that locks into the diffuser, ensuring optimal conductivity and cooler operation.

This 15-foot model gives you the freedom to move around your shop or garage without dragging your welder constantly. It comes ready to feed .030-.035 inch wire right out of the box and is compatible with a wide range of Miller machines. Whether you are restoring a classic car, fixing farm equipment, or building custom furniture, the MDX-100 delivers the professional arc stability and comfort you need to lay down perfect beads every time.

Why Welders Choose the MDX-100:

  • Zero Fatigue: Rubberized grip and rear swivel make maneuvering effortless.
  • Flawless Feeding: Locked liner system prevents birdnesting and erratic arcs.
  • Plug-and-Play: Direct replacement for M-100 guns on Millermatic 141/211 and Multimatic 215/220.
  • Longer Reach: 15-foot cable allows for greater mobility around the shop.
