The Lincoln Electric KP42-25-15 is a premium replacement cable liner designed to restore the efficiency of your MIG welding setup. Compatible with the Magnum 250L and the modern Magnum PRO Curve 200/HDE 250 series guns, this liner is an essential maintenance item for welders using small diameter wires. It is specifically calibrated for wire sizes between .025" and .030", providing the tight tolerance needed to support the wire without causing excessive drag.
Constructed from wound steel monocoil, this liner offers superior durability and flexibility. The 15-foot length is standard for many shop-floor MIG guns, allowing for extended reach without compromising feedability. A degraded liner is one of the most common causes of welding issues; a kinked or dirty liner can increase the load on your wire feeder motor and cause irregular arc characteristics. By installing a fresh KP42-25-15 liner, you ensure that the wire travels smoothly from the feeder to the contact tip.
Installation is straightforward. The liner is fed through the back of the gun and trimmed to the appropriate stick-out length at the front end, ensuring seamless contact with the gas diffuser. Whether you are performing automotive bodywork with .025" wire or general light fabrication with .030" wire, this liner provides the reliability professional welders demand. Keep your Magnum gun operating at peak efficiency with this genuine Lincoln Electric component.
