The ESAB PSF Teflon Liner (Part Number 0457969883) is a specialized consumable designed to enhance the performance of ESAB PSF series MIG guns. Engineered specifically for the challenges of welding with soft filler metals, this liner is constructed from high-grade Polytetrafluoroethylene (PTFE), commonly known as Teflon. Unlike standard steel liners which can cause friction and shaving on soft wires, this PTFE liner provides an exceptionally smooth, low-friction path for the welding wire to travel from the drive rolls to the contact tip.
This specific liner measures 4.5 meters in length, making it suitable for standard length torch cable assemblies. It is sized to accommodate wire diameters ranging from 1.0mm to 1.2mm, covering the most common sizes used in industrial aluminum fabrication. The use of a Teflon liner is mandatory when welding aluminum to prevent "bird-nesting" at the feeder and to ensure a consistent arc. It is also highly recommended for stainless steel applications to prevent cross-contamination from carbon steel liners.
Proper maintenance of the wire feeding path is critical for weld quality. Over time, liners can accumulate dust or become kinked, leading to erratic feeding. Replacing your liner with a genuine ESAB 0457969883 ensures that your equipment operates within factory specifications. When installing, it is important to ensure the liner is cut to the correct length and properly seated to avoid gaps where the wire could buckle. For aluminum applications, this liner is often used in conjunction with a brass neck liner (jump liner) in the torch head to withstand the higher heat at the front end.
