OVERVIEW

Smooth Aluminum Wire Feeding for Miller Guns

Welding aluminum requires precision and the right equipment to avoid common headaches like bird-nesting and erratic arc stability. The Miller Style Teflon Liner is engineered specifically to address the challenges of feeding soft aluminum wire through your MIG gun cable. Designed for use with .030" to .035" (0.8mm - 0.9mm) wire, this liner features a low-friction Teflon (PTFE) core that allows the wire to glide smoothly from the feeder to the contact tip.

Standard steel liners are abrasive and can scrape soft aluminum wire, creating shavings that clog the liner and lead to feed failures. This Teflon replacement eliminates that friction, ensuring your wire remains intact and feeds at a consistent speed. It is fully compatible with popular Miller M-Series MIG guns, including the M-10, M-15, M-25, and M-40 models often found on Millermatic machines. Whether you are fabricating aluminum boat parts, repairing automotive components, or performing general maintenance, this liner is a critical upgrade for your setup.

Installation is straightforward. The liner comes in a standard length (typically 15 feet) that accommodates most gun assemblies and can be easily trimmed to exact specifications. By switching to a dedicated Teflon liner, you significantly reduce downtime caused by feed jams, allowing you to focus on laying down high-quality aluminum welds.

Key Benefits

  • Friction Reduction: PTFE material minimizes drag on soft wires.
  • Compatibility: Fits standard Miller M-Series guns found on Millermatic welders.
  • Durability: Resists kinking and wear during regular use.

FAQ

Aluminum wire is much softer than steel. A steel liner can shave the aluminum wire, causing clogging and friction. Teflon provides a smooth, low-friction surface that prevents these issues and ensures consistent feeding.

This liner is designed for .030" to .035" (0.8mm to 0.9mm) welding wire.

It is compatible with Miller M-Series MIG guns, including models M-10, M-15, M-25, and M-40.

It is not recommended. Steel wire is abrasive and will wear out the soft Teflon liner very quickly. You should use a steel wound liner for steel wire.

Remove the nozzle, contact tip, and gas diffuser. Remove the old liner from the back of the gun. Insert the new Teflon liner, ensuring it seats fully. Trim the excess length at the back end according to your gun's manual, then reinstall the front-end consumables.

While a spool gun is often best for aluminum, using a Teflon liner in a standard MIG gun is a cost-effective alternative for short distances (usually up to 10-12 feet) and stiffer aluminum alloys.

This is a high-quality aftermarket replacement part designed to meet or exceed the specifications of the original Miller equipment.
