Upgrade or repair your Miller MIG gun with this high-performance Teflon Liner, specifically designed for feeding .030" to .035" aluminum wire. If you are experiencing feed issues, burn-back, or bird-nesting while welding aluminum, the culprit is often an incorrect or worn-out liner. Steel liners are not suitable for aluminum; you need the smooth, non-abrasive surface of Teflon to ensure reliable wire delivery.
This liner is a direct fit for Miller M-Series MIG guns (M-10, M-15, M-25, and M-40), making it an essential consumable for owners of Millermatic 135, 140, 175, 180, 210, 211, and 250/251/252 series welders equipped with these guns. The liner supports the wire along the entire length of the cable, preventing it from buckling under the pressure of the drive rolls. This is particularly important for smaller diameter aluminum wires like .030" and .035", which lack the column strength of steel wire.
To install, simply remove the old liner, unroll the new Teflon liner, and slide it into the gun cable. Ensure the liner is fully seated before trimming any excess at the back end. Using the correct liner is the single most effective way to improve your aluminum MIG welding results without investing in a spool gun. Keep your production line moving and your welds clean with this professional-grade replacement part.
