0366550884 - ESAB PSF Teflon Liner for 0.9mm Aluminum Wire - 3m Length

Optimized Wire Feeding for Aluminum Applications

The ESAB PSF Aluminum Liner (0366550884) is a critical component for professionals welding aluminum with ESAB PSF series MIG guns. Designed specifically for 0.9mm (0.035") aluminum wire, this liner addresses the unique challenges associated with feeding soft alloys. Unlike steel liners, which can shave aluminum wire and cause friction, this liner utilizes a low-friction polymer material (typically PTFE or similar) to ensure smooth, consistent delivery of the wire to the contact tip.

With a length of 3 meters (approximately 10 feet), it is perfectly sized for standard length PSF torches. The precision engineering of this genuine ESAB part minimizes the gap between the wire and the liner wall, providing excellent column strength while reducing drag. This is essential for preventing "bird-nesting" at the drive rolls and ensuring a stable arc during welding operations. Proper maintenance of your MIG gun's liner is the first step in troubleshooting erratic wire feeding, and for aluminum applications, using the correct liner material is non-negotiable.

Installation is straightforward, fitting directly into the rear connector of compatible PSF guns. Whether you are working in automotive repair, boat building, or general aluminum fabrication, this liner helps maintain high productivity by reducing wire feeding issues. It is recommended to check the liner periodically for kink damage or debris buildup and replace it to maintain optimal weld quality.
