Tweco 1440-1904 Conduit Liner 1/16 Inch 10 Ft Fusion Pro

Product Description

The TWECO 1440-1904 is a conduit liner designed for use with FUSION Pro MIG welding guns. It guides the welding wire from the drive rolls through the gun cable to the contact tip, reducing friction and preventing wire feeding problems during operation. This liner accommodates wire up to 1/16 inch in diameter and measures 10 feet in length, making it compatible with standard-length MIG gun assemblies. Proper liner selection and condition directly affect wire feed consistency, arc stability, and overall weld quality. Welding technicians and fabricators typically replace liners as part of routine gun maintenance or when feed irregularities develop.

This liner is intended for FUSION Pro series MIG welding guns. It suits applications in light industrial, maintenance, and fabrication environments where consistent wire delivery is critical. The 10-foot length fits full-length gun cable assemblies without modification. Replacement of worn or kinked liners is a standard preventive maintenance task performed between jobs or during scheduled downtime to maintain wire feed performance.

Installation Notes

Liner replacement is performed by qualified welding equipment technicians or experienced welders. Disconnect the welding gun from the wire feeder and power source before beginning any service. Remove the contact tip and nozzle, then pull the old liner from the gun cable before threading the new liner through from the feeder end. Trim the liner to the correct length per the gun manufacturer's guidelines and reinstall all consumables before returning the gun to service.
