OVERVIEW

High-Performance Teflon Liner for Aluminum Welding

The Miller M1508 Teflon Liner is a critical component for industrial welding operations utilizing aluminum wire. Unlike standard steel liners, which are designed for hard wires like mild steel, this liner is manufactured from high-quality Polytetrafluoroethylene (PTFE), commonly known as Teflon. This material provides an exceptionally low coefficient of friction, which is essential when feeding soft, pliable aluminum wires. The liner is sized specifically for wire diameters ranging from .047" (3/64") to .062" (1/16"), covering the most common gauges used in structural and fabrication aluminum welding.

In professional fabrication environments, wire feeding issues are a primary cause of downtime. Aluminum wire, being softer than steel, is prone to buckling, shaving, and "birdnesting" at the drive rolls if it encounters resistance within the gun cable. The M1508 liner mitigates these risks by providing a smooth, snag-free path for the wire to travel from the feeder to the contact tip. This results in a stable arc, consistent deposition rates, and higher quality welds with fewer defects. It is compatible with a range of Miller MIG guns, ensuring seamless integration into existing equipment setups.

Key Technical Specifications:

  • Material Composition: Pure PTFE (Teflon) for maximum lubricity.
  • Wire Compatibility: Optimized for 4043 and 5356 aluminum alloys.
  • Diameter Range: Accommodates .047" (3/64") through 1/16" wires.
  • Thermal Stability: Resists heat buildup during extended welding cycles.

For maintenance and repair operations (MRO), keeping a stock of M1508 liners is recommended to prevent production halts. Over time, even Teflon liners can accumulate aluminum oxide dust or become kinked, necessitating replacement to maintain optimal performance. This product meets or exceeds OEM specifications for fit and function, providing a reliable solution for demanding aluminum welding tasks.

FAQ

Aluminum wire is much softer than steel. A steel liner creates too much friction, causing the aluminum wire to buckle, shave, or birdnest. Teflon reduces friction significantly, allowing smooth feeding.

This liner is designed for wire diameters from .047" (3/64") up to .062" (1/16").

It is not recommended. Steel wire is abrasive and will quickly wear through the soft Teflon material, ruining the liner.

Use a sharp knife or a dedicated liner cutter to ensure a clean, flat cut. Do not use side cutters, as they can pinch the tube and restrict wire flow.

It fits many standard Miller MIG guns, but you should verify your specific gun model's manual to ensure it accepts the M1508 series liners.

Some Teflon liners require a brass neck liner or jumper for the hot front end of the gun. Check your gun's schematic to see if a separate neck liner is required.

If the liner is too long, it will be compressed when the gun is assembled, causing it to snake inside the cable. This creates friction and feeding issues. Always trim to the correct stick-out length.
