KP45H-332-25 - Lincoln Electric KP45H-332-25 Magnum PRO Cable Liner 25ft (5/64-3/32)

Reliable Wire Feeding for Industrial Applications

The Lincoln Electric KP45H-332-25 Cable Liner is a critical component designed to ensure the smooth and uninterrupted delivery of welding wire in high-demand industrial environments. Engineered specifically for the Magnum PRO series, this liner is compatible with both Semi-Auto MIG guns and Robotic Torches. Its robust construction is tailored to handle larger wire diameters ranging from 5/64 inch to 3/32 inch (2.0 mm to 2.4 mm), making it an essential consumable for heavy fabrication and structural welding tasks where consistent deposition rates are required.

With an extended length of 25 feet (7.6 meters), this liner is ideal for setups requiring significant reach, such as boom-mounted wire feeders or robotic cells where the torch must articulate over large workpieces. The internal geometry of the liner is precision-manufactured to minimize friction and drag, which are common causes of wire feeding issues like bird-nesting or burn-back. By maintaining a low coefficient of friction, the KP45H-332-25 protects the integrity of the wire surface and ensures stable electrical contact at the contact tip.

Regular maintenance of the wire delivery system is paramount for achieving high-quality welds. Over time, liners can accumulate dust, metal shavings, and lubricant residue, leading to erratic arc performance. Replacing worn liners with genuine Lincoln Electric parts restores the gun's performance to factory specifications. This liner is built to withstand the mechanical stresses of daily use, resisting kinking and crushing that can occur in dynamic welding environments. Whether used in manual welding stations or automated production lines, the KP45H-332-25 delivers the reliability professional fabricators demand.
