258542 - Miller Jump Liner Assembly 3/64-1/16 Inch (5-Pack)

Genuine Miller Jump Liner Assembly for Precision Wire Feeding

The Miller 258542 Jump Liner Assembly is a critical replacement component designed to maintain the optimal performance of your MIG welding operations. Engineered specifically for wire diameters ranging from 0.047 inches (3/64") to 0.062 inches (1/16"), this liner assembly ensures that welding wire travels smoothly through the neck of the welding gun. In industrial environments where downtime equates to lost revenue, utilizing genuine Miller parts guarantees compatibility and reliability. This package contains five (5) individual jump liner assemblies, allowing facility managers and procurement specialists to stock essential consumables efficiently.

Jump liners are particularly important in systems feeding softer wires, such as aluminum, where friction and resistance must be minimized to prevent feeding issues. The 258542 assembly bridges the gap in the gun's neck, a common stress point for wire delivery. By maintaining a fresh liner in this section, operators can reduce the risk of micro-arcing and wire shaving inside the gun, which can lead to poor weld quality and equipment damage. This product is manufactured to Miller's high standards for durability and dimensional accuracy.

Regular inspection and replacement of the jump liner are recommended as part of a preventative maintenance schedule. As the liner wears, the internal surface can become rough or clogged with debris, increasing drag on the wire. This 5-pack configuration is ideal for high-volume welding stations, ensuring that a replacement is always on hand when wear is detected. Trust in Miller Electric's engineering to keep your production lines moving with consistent arc stability and wire delivery.
