0459990074 - ESAB PA/Bronze Neck Liner for 1.2-1.6mm Wire

Reliable Wire Feeding for ESAB Torches

The ESAB Neck Liner PA/Bronze 1.2-1.6mm (0459990074) is a specialized replacement component designed to maintain optimal wire feeding performance in your ESAB MIG welding gun. Located within the swan neck of the torch, this liner bridges the gap between the main cable liner and the contact tip, ensuring that welding wire travels smoothly through the bend of the gun without binding or shaving.

Constructed from a specific PA (Polyamide) and Bronze combination, this liner is engineered to offer the best of both worlds: the low-friction characteristics needed for feeding soft wires—such as aluminum—and the durability required to withstand the high temperatures generated near the welding arc. Standard steel liners can cause contamination in aluminum welds, while pure plastic liners may melt in the high-heat zone of the neck. This bronze-enhanced solution solves those issues, providing a heat-resistant, low-friction path for 1.2mm to 1.6mm (0.045" to 1/16") wires.

Regular maintenance of the neck liner is essential for preventing wire feed issues like bird-nesting or erratic arc stability. If you are experiencing drag or resistance in your wire feed system, especially when the torch is bent, a worn neck liner is often the culprit. Replacing it with this genuine ESAB part restores the smooth, consistent delivery of wire necessary for high-quality welds.
