OVERVIEW

Error-Proof Liner Replacement for Miller MDX Guns

The Miller AccuLock™ MDX™ MIG Gun Liner (LMD3A-15) is engineered to simplify maintenance and improve the reliability of your welding operations. Designed specifically for use with Miller MDX-250 MIG guns, this 15-foot liner accommodates wire diameters ranging from .035" to .045". The standout feature of the AccuLock system is its error-proof installation process. Unlike traditional liners that require careful measuring and trimming, the AccuLock liner loads from the front of the gun and locks securely in place. It is then trimmed flush with the power pin cap at the back, ensuring a perfect fit every time without the guesswork.

Improper liner length is a leading cause of wire-feeding issues, but the LMD3A-15 eliminates this variable entirely. By ensuring the liner is always the correct length, it prevents gaps or compression that can lead to erratic arcs. This liner is compatible with both solid and flux-cored wires, making it a versatile choice for various industrial applications. Whether you are in a high-production fabrication shop or a maintenance facility, the ease of replacement means less downtime and more arc-on time.

Key Benefits for Maintenance

  • No Measuring Required: The front-loading design automatically sets the correct length.
  • Universal Fit for MDX-250: specifically tailored for 15-foot cable assemblies.
  • Reduced Downtime: Quick change-outs mean your welders get back to work faster.

Invest in genuine Miller AccuLock consumables to maintain the integrity of your welding equipment. The LMD3A-15 provides the durability and precision required for consistent, high-quality welds.
