LMD2A-15 - Miller LMD2A-15 AccuLock MDX Liner .030-.035 15ft

Reliable Wire Feeding for MDX-250 Guns

The Miller LMD2A-15 AccuLock MDX MIG Gun Liner is a premium replacement component designed specifically for the Miller MDX-250 MIG gun series. Engineered to handle wire diameters between .030" and .035", this 15-foot liner ensures smooth and consistent wire delivery during your welding operations. A worn or kinked liner is a common cause of erratic arcs and feeding problems; replacing it with a genuine Miller AccuLock liner restores your equipment's performance to factory standards.

Innovative AccuLock Design

Miller has addressed the common frustrations of liner replacement with the AccuLock system. Unlike traditional liners that require careful measuring and guesswork, the LMD2A-15 is designed to be loaded from the front of the gun. Once inserted, it locks securely into place at the diffuser end. The operator simply trims the excess flush with the power pin cap at the back of the gun. This "error-proof" installation method guarantees the liner is exactly the right length every time, preventing gaps or compression that lead to bird-nesting.

Performance and Compatibility

This liner is essential for welders using the MDX-250 gun for general fabrication or auto body work. By ensuring the contact tip is perfectly aligned and centered with the liner lock, the system creates a flawless path for the wire. This reduction in friction and misalignment significantly minimizes burnbacks and downtime. Whether you are running solid steel wire or flux-cored options within the specified diameter range, the LMD2A-15 provides the durability and precision required for high-quality welds.

Key Benefits:

• Eliminates liner trim measurement errors.
• Reduces wire chatter and feeding resistance.
• Direct replacement for the legacy LM2A-15 part.
