LM2A-10 - Miller LM2A-10 AccuLock MDX Liner .030-.035 10ft

Upgrade Your Wire Feeding with the Miller LM2A-10 AccuLock Liner

Struggling with erratic wire feeding, burnbacks, or the dreaded birdnest at your drive rolls? The issue might not be your machine settings—it could be your liner. The Miller LM2A-10 AccuLock™ MDX™ Liner is designed to take the headache out of MIG gun maintenance and get you back to welding with a stable, smooth arc. Specifically built for 10-foot Miller MDX series guns and .030-.035 inch wire, this liner features a revolutionary design that fixes the alignment problems found in older style guns.

The standout feature of this liner is its error-proof replacement process. We've all been there: trying to measure a new liner against the old one, or using a chart to cut it to a specific length, only to find it's slightly off when installed. A gap as small as a fraction of an inch can cause the wire to shave, clog, or arc erratically. Miller solves this with the AccuLock system. You simply feed the liner in from the front of the gun until it locks. Then, you go to the back of the gun (the power pin end) and trim the excess liner flush with the cap. No measuring tapes, no guessing, and no mistakes. The liner is perfectly seated at the front, ensuring the wire transitions smoothly from the liner to the contact tip.

This smooth transition is critical for consistent welding performance. By centering the contact tip with the liner lock, the LM2A-10 creates a straight, uninterrupted path for the wire. This reduces drag, which is especially helpful when feeding softer wires or when the gun cable is bent during out-of-position welding. The result is a steady arc, less spatter, and longer consumable life. Whether you are a hobbyist in a garage or a professional on the production line, using the correct OEM liner for your MDX gun is the easiest way to improve your weld quality. Don't let a bad liner ruin your bead; upgrade to the error-proof AccuLock MDX system.
