M1115 - Miller M1115 Replacement MIG Liner 15ft .110 ID

Precision Wire Delivery for MIG Systems

The Miller M1115 Liner is a high-quality replacement component designed to restore the performance of your MIG welding gun. Engineered with a length of 15 feet, this liner is specifically manufactured to fit gun cable assemblies requiring a liner with an Outer Diameter (OD) of .187 inches and an Inner Diameter (ID) of .110 inches. The liner features a robust steel spiral construction that provides the necessary flexibility to navigate the gun cable while maintaining enough rigidity to prevent collapsing or kinking under normal shop conditions.

Proper wire guidance is essential for maintaining a stable arc and consistent weld bead profile. The M1115 utilizes a smooth internal surface to minimize friction against the welding wire, reducing the load on the wire feeder motor and preventing slip. This specific model comes equipped with a retention ring (often a brass collet or washer style) at the back end, ensuring a secure mechanical connection to the power pin or gun block. This prevents the liner from walking or retracting during operation, which can lead to gas leakage or wire feed interruptions.

Regular maintenance of the wire conduit is a standard procedure in industrial welding environments. Over time, liners accumulate metal shavings, dust, and lubricant residue, which increases drag. Replacing your old liner with the Miller M1115 ensures that your equipment operates within its optimal parameters, delivering wire smoothly from the drive rolls to the contact tip.
