0349303018 - ESAB Steel Liner for PSF Torches 0.035-0.045 (3m)

Smooth Wire Feeding for Your ESAB PSF Torch

Is your wire stuttering or jamming during a weld? The culprit is often a dirty or worn-out liner. The ESAB 0349303018 Steel Liner is the genuine replacement part you need to restore the performance of your ESAB PSF MIG gun. Designed for the professional welder, this liner ensures that your welding wire glides smoothly from the feeder to the workpiece, giving you the consistent arc control required for high-quality welds.

This liner is specifically sized for the most common wire diameters used in general fabrication: 0.035" to 0.045" (0.9mm to 1.2mm). If you are running standard solid steel wire, this steel spiral liner offers the durability and low friction needed for long shifts. It comes in a 3-meter (10 ft) length, which fits standard PSF 250, 305, 405, and 505 torches. If your torch is shorter, the liner can be trimmed to fit; always ensure you measure twice and cut once, filing down any sharp edges to prevent wire shaving.

Why Replace Your Liner?
Over time, liners clog with shop dust, drawing lubricant, and metal flakes from the wire. This increases drag on the wire feeder, leading to burn-backs and erratic beads. Swapping out your liner is one of the cheapest and most effective ways to tune up your welder. Keep a few of these ESAB liners in your maintenance kit so you aren't caught off guard in the middle of a job.

Installation Tips:
When installing, lay your torch cable out straight to ensure the new liner slides in without kinking. Blow out the torch cable with compressed air before inserting the new liner to remove any old debris. Secure the liner firmly at the back end and trim the front flush according to your torch manual's specifications for optimal gas flow and current transfer.
