Pro-source 44-564-15 Mig Welder Wire Liner 15 Foot

Product Description

The PRO-SOURCE 44-564-15 is a MIG welder wire liner designed for use with Tweco welding guns. The liner guides the wire electrode through the welding cable assembly, maintaining consistent wire feed and reducing friction that can cause birdnesting or erratic arc performance. It is rated for a wire diameter of 0.0781 inches and measures 15 feet in overall length, making it suitable for standard MIG gun setups found in fabrication shops, maintenance facilities, and industrial welding operations. Licensed welders and shop technicians install and replace these liners as part of routine gun maintenance.

This wire liner fits into Tweco-style MIG welding gun assemblies and is used wherever that gun platform is in service, including light industrial, manufacturing, and repair welding applications. At 15 feet in length, it covers the full cable run of most standard Tweco gun configurations. Replacement is typically performed when wire feeding becomes inconsistent, the liner shows visible wear, or after high-volume production runs that accelerate liner degradation.

Compatibility

Designed for use with Tweco MIG welding gun assemblies, as specified by the manufacturer. Verify gun model and liner retention hardware before installation to confirm correct fit.

Installation Notes

Wire liner replacement is performed by welders or qualified shop technicians. Before replacing the liner, disconnect the welding gun from the wire feeder and remove the contact tip and nozzle to allow full access to the liner. Thread the new liner carefully through the cable without kinking, and trim to the correct length if required by the gun manufacturer. Always verify wire feed tension and drive roll condition after liner installation to confirm smooth operation.
