Tweco 1440-1012 Conduit Liner Wire Feed

Product Description

The TWECO 1440-1012 is a conduit liner designed for use in MIG welding gun assemblies. Conduit liners guide the welding wire from the wire feeder through the gun cable and out to the contact tip, protecting the wire path and maintaining consistent feed performance. A worn or damaged liner is one of the most common causes of wire feed problems, including birdnesting and arc instability. This replacement liner is a direct-fit component intended for installation by welding technicians and maintenance professionals servicing MIG gun setups in light industrial, fabrication, and manufacturing environments.

This liner is suited for use in wire feed welding systems where a replacement conduit liner is required to restore proper wire feed function. It is installed inside the gun cable assembly and must be matched to the correct wire diameter and gun cable length for the application. Consult the gun manufacturer specifications to confirm correct liner sizing before installation.

Key Features

• Guides welding wire through MIG gun cable to maintain consistent feed
• Replacement of worn liners reduces wire feed problems and arc instability
• Compact form factor suited for standard MIG gun cable assemblies

Installation Notes

Conduit liner replacement is performed by qualified welding equipment technicians or maintenance personnel. Before servicing, disconnect the welding machine from its power source and ensure the wire feeder is fully de-energized. Remove the nozzle, contact tip, and diffuser before extracting the existing liner from the gun cable. Trim the new liner to the correct length per the gun manufacturer guidelines before reinstalling all components.
