0700300470 - ESAB PSF Steel Neck Liner 1.2-1.6mm Replacement

Genuine ESAB Steel Neck Liner for PSF Series Torches

The ESAB 0700300470 Neck Liner is a specialized replacement component designed to maintain the integrity of the wire feed path within the swan neck of ESAB PSF MIG guns. Unlike the main conduit liner which runs the length of the cable assembly, the neck liner resides specifically within the curved torch neck (swan neck). This area is subject to the highest friction and mechanical stress as the welding wire is forced to change direction before exiting the contact tip. Over time, the internal surface of the neck liner can wear, become clogged with shavings, or develop grooves that impede smooth wire delivery.

This specific liner is manufactured from high-quality steel spiral, optimized for use with steel welding wires ranging from 1.2mm to 1.6mm (0.045" to 1/16"). It is engineered to provide the correct internal clearance for these diameters, preventing the wire from buckling (birdnesting) while minimizing drag. Proper maintenance of the neck liner is essential for industrial welding operations using ESAB equipment, as a worn liner is a frequent, yet often overlooked, cause of micro-arcing inside the tip adapter and unstable arc characteristics.

Compatible primarily with the heavy-duty ESAB PSF series torches (such as the PSF 405 and PSF 505), this component ensures that your welding system operates at peak efficiency. Regular inspection and replacement of the neck liner during scheduled maintenance intervals can significantly extend the life of your contact tips and reduce unscheduled downtime.
