OVERVIEW

Optimize Your MIG Gun Performance

Keep your welding operations running smoothly with the Miller 258726 Head Tube Liner Assembly. This genuine Miller replacement part is a "jump liner" specifically designed for the head tube (neck) section of compatible MIG welding guns. The neck of the gun is subjected to intense heat and tight bending radii, which can cause standard liners to kink or clog with shavings. This 15-inch liner assembly addresses that specific problem area, providing a fresh, smooth path for your welding wire right before it enters the contact tip.

Compatible with wire sizes .030" through .035", this liner is versatile enough for light-to-medium gauge fabrication work. It is particularly useful in setups involving push-pull guns or extended reach guns where minimizing friction is paramount to arc stability. A worn head tube liner can lead to erratic wire feeding, burn-back, and increased downtime. By swapping out this component regularly, you ensure that your wire feeds consistently, resulting in better bead profile and less spatter.

Sold in a convenient 5-pack, the Miller 258726 is a must-have consumable for any professional welder's toolkit. It installs quickly into the head tube assembly, minimizing downtime during maintenance intervals. Using genuine Miller consumables guarantees that the liner material and dimensions meet the exact specifications of your equipment, preventing fitment issues and ensuring long-lasting durability even in harsh industrial environments.

FAQ

A head tube liner, or jump liner, guides the welding wire through the curved neck of the MIG gun. This area experiences the most friction and heat, so a specialized liner helps maintain smooth wire feeding.

This liner assembly is designed for welding wires with diameters between .030 inches and .035 inches.

The Miller 258726 liner is 15 inches long, designed specifically for the head tube section of the gun.

No, this is a jump liner intended only for the neck/head tube of the gun, not the entire length of the cable assembly.

This product is sold as a pack of 5 liners.

Using a jump liner allows you to replace only the high-wear section in the gun's neck without having to replace the more expensive main liner, saving money and maintenance time.

Yes, jump liners are frequently used in push-pull guns for aluminum welding to reduce friction in the bend.
