14401013 - Tweco 44TF11615 Teflon Liner for 1/16 Aluminum Wire, 15ft

Tweco 44TF11615 Teflon Conduit Liner for Aluminum Welding

The Tweco 44TF11615 is a specialized conduit liner designed to address the unique challenges of feeding aluminum welding wire. Unlike steel liners, which can cause friction and shave soft aluminum wires leading to clogged tips and erratic feeding, this liner is constructed from high-quality Teflon (PTFE). The low-friction surface allows 1/16-inch (1.6mm) aluminum wire to glide smoothly through the cable assembly, ensuring a stable arc and consistent weld bead profile.

Measuring 15 feet in length, this liner is suitable for standard length MIG gun cables. It is part of the Tweco 44 Series, making it a direct replacement for compatible Tweco MIG guns. Proper wire feeding is critical in aluminum MIG welding to prevent "bird-nesting" at the drive rolls; upgrading to a Teflon liner is the first step in optimizing your setup for aluminum fabrication. Whether you are working in automotive repair, boat building, or general fabrication, this liner provides the reliability needed for high-quality aluminum welds.

Installation is straightforward, fitting directly into the gun connector and extending to the contact tip. Users should ensure the liner is trimmed correctly to fit their specific gun assembly to prevent gaps where the wire is unsupported. This product is an essential consumable for any welder switching their equipment from steel to aluminum applications.
