112715 - Miller 15ft MIG Gun Liner Conduit Assembly

Restore Precision Wire Delivery

The Miller 112715 is a 15-foot conduit assembly, commonly referred to as a liner, designed for specific Miller MIG guns. This component is the backbone of the wire feeding system within the gun cable, providing a guided path for the welding wire from the feeder to the contact tip. For professional welders, the tactile feel of the arc is heavily dependent on how smoothly the wire travels. A compromised conduit introduces friction and drag, which manifests as a sputtering arc or irregular bead profile.

This conduit is constructed to withstand the rigors of industrial environments. It features a durable coil design that resists collapsing while maintaining flexibility, allowing the gun cable to be maneuvered around workpieces without pinching the wire. The 15-foot length is a standard size for many MIG gun configurations, offering ample reach for various fabrication setups. The inclusion of the fitting at the back end ensures a secure connection to the power pin or feeder interface, preventing gas leaks or mechanical separation during operation.

Maintenance of the conduit is often overlooked until failure occurs. Proactive replacement of the Miller 112715 is recommended whenever wire feeding becomes sluggish or after a specific duration of arc time, depending on the wire type and shop conditions. Using this OEM conduit guarantees that the inner diameter and material hardness are optimized for the wire types typically used with Miller guns, minimizing shaving generation and maximizing the lifespan of the liner itself. It is a critical spare part for any shop relying on Miller MIG equipment.
