Lincoln Electric KP3543-35116-25 Liner for Magnum PRO AL Guns

Maximize the performance of your push-pull welding system with the Lincoln Electric KP3543-35116-25 Aluminum Liner. Designed as a direct replacement for Magnum® PRO AL PA and PW model guns, this liner is engineered to facilitate the smooth transfer of aluminum welding wire over a 25-foot distance. The liner's internal composition is specifically selected to handle the softness of aluminum wire, preventing the shaving, clogging, and drag that typically occur with standard steel liners.

This liner supports wire diameters ranging from .035" (0.9 mm) to 1/16" (1.6 mm), covering a broad spectrum of welding procedures. In push-pull systems, the synchronization between the cabinet feeder and the gun motor is delicate; a worn or incorrect liner can disrupt this balance, leading to burn-backs or erratic feeding. By using the OEM KP3543-35116-25 liner, you ensure that your equipment operates within its designed parameters, delivering consistent wire speeds and high-quality welds.

Technical Specifications and Application

The 25-foot length matches standard cable assemblies for the Magnum PRO AL series, ensuring a precise fit without the need for modification. The liner installs easily into the gun cable, seating securely to prevent gas leaks or wire misalignment. It is an indispensable component for welders working on large-scale aluminum projects where equipment reliability is paramount.

At Welders Supply, we recommend inspecting your liner regularly and replacing it at the first sign of wear or kinking. Keeping a fresh KP3543-35116-25 liner in your maintenance kit ensures you are always ready to tackle aluminum jobs with confidence and precision.
