LM2A-15 - Miller AccuLock MDX Liner .030-.035 Wire 15ft LM2A-15

Error-Proof Liner Replacement for MDX MIG Guns

Stop struggling with wire feeding issues and get back to welding with the Miller LM2A-15 AccuLock™ MDX™ Liner. Designed for use with the popular MDX-250 MIG gun, this liner handles 0.030" to 0.035" wire diameters and fits 15-foot cable assemblies. If you have ever experienced the frustration of a bird-nest at the drive rolls or an unstable arc that sputters and pops, a worn or improperly installed liner is often the culprit. Miller has revolutionized liner replacement with the AccuLock system, making it virtually impossible to install incorrectly.

The genius of the AccuLock MDX design lies in its front-loading capability. Instead of feeding the liner from the back and guessing where to cut, you simply insert the LM2A-15 into the front of the gun neck. It locks securely in place, ensuring the front end is perfectly positioned relative to the contact tip. You then trim the excess liner flush at the back of the power pin. No measuring tapes, no calculations, and no gaps. This precise fit guarantees that your wire has a smooth, straight shot through the gun, minimizing friction and drag.

Why does this matter? A smooth wire path means consistent wire stick-out and a stable arc. When the contact tip is aligned and centered with the liner lock, the wire feeds without wandering. This reduction in friction not only improves weld quality but also extends the life of your drive rolls and contact tips. The LM2A-15 is built to Miller's high standards of durability, resisting kinking and crushing during daily use.

This liner is specifically optimized for mild steel wire applications. If you are fabricating steel structures, repairing automotive frames, or performing general maintenance, the LM2A-15 is the correct choice for your 15-foot MDX-250 setup. Don't let a cheap or worn-out liner ruin your welds. Upgrade to the Miller AccuLock MDX liner and experience the difference that perfect alignment and error-proof installation can make in your daily work.
