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

Genuine ESAB Replacement Neck Liner

Keep your welding operations running smoothly with the ESAB 0459990074 Neck Liner. This component is a critical wear part for welders using ESAB MIG guns, specifically tailored for wire diameters ranging from 1.2mm to 1.6mm. The neck liner sits inside the curved swan neck of the torch, a high-stress area where wire friction and heat are most intense.

When welding with aluminum or stainless steel, minimizing friction is paramount to prevent wire deformation and feedability issues. This liner utilizes a PA/Bronze composition. The bronze component provides excellent thermal conductivity and resistance to the radiant heat of the arc, preventing the liner from deforming or melting inside the neck. Simultaneously, the material composition ensures a smooth surface finish that allows soft wires to glide through the torch bend with minimal resistance.

Over time, neck liners can become clogged with debris, kinked, or worn down by the abrasive action of the wire. A compromised liner leads to micro-arcing inside the neck, erratic wire speeds, and frustration for the operator. By installing a fresh ESAB PA/Bronze neck liner, you ensure that your equipment operates at peak efficiency, delivering the consistent wire stick-out and arc control required for professional fabrication.
