OVERVIEW

Smooth Aluminum Feeding with Tweco Teflon Liners

Welding aluminum can be a headache, especially when your wire won't feed smoothly. The "bird-nesting" at the drive rolls or the erratic arc caused by friction in the gun cable can ruin your welds and your patience. The Tweco 35TF-40-10 Teflon Conduit is the solution designed to fix exactly these problems. If you are running a Tweco MIG gun and need to switch over to aluminum, swapping out your steel liner for this Teflon version is the first and most important step.

This 10-foot liner is made from high-grade PTFE (Teflon), which is slick and smooth, allowing soft aluminum wire to glide through the gun cable with minimal resistance. It is sized perfectly for the most common aluminum wire diameters: 0.035" and 3/64". Whether you are repairing a boat hull, fabricating an aluminum tank, or working on custom automotive parts, this liner ensures that the wire is delivered to the contact tip consistently, giving you a stable arc and a clean bead.

Designed to fit the popular Tweco No. 3 and No. 4 guns, as well as the Spray Master series, this is a genuine Tweco part that guarantees a perfect fit. Don't struggle with feeding issues or try to force aluminum through a dirty steel liner. Upgrade to the 35TF-40-10 and experience the difference a proper conduit makes in your aluminum welding projects. Remember to keep your gun cable as straight as possible during operation for the best results!

FAQ

This liner is designed for wire sizes ranging from 0.035 inches (0.9 mm) to 3/64 inches (1.2 mm).

No, it is not recommended. Steel wire is abrasive and will quickly cut into the soft Teflon material, ruining the liner. Use steel wound liners for steel wire.

It fits Tweco No. 3 and No. 4 series guns, as well as Tweco Spray Master 350 and 450 series guns.

Aluminum wire is soft and easily damaged. A Teflon liner reduces friction, preventing the wire from buckling, shaving, or tangling inside the cable.

The liner is 10 feet (approximately 3 meters) long.

Yes, Tweco conduit liners typically come with the necessary back-end hardware (collet/stop) attached for installation into the gun.

Remove the old liner, unroll the new Teflon liner, insert it through the back of the gun, and trim the front end to the correct length according to your gun's manual.
