KP3543-35116-15 - Lincoln KP3543-35116-15 Aluminum Liner 15ft for Magnum PRO AL

Reliable Performance for Aluminum Welding Applications

Achieve superior wire feeding performance with the Lincoln Electric KP3543-35116-15 Liner, specifically manufactured for aluminum welding applications. Aluminum welding requires precision equipment to handle the softness of the filler metal, and the liner is often the unsung hero of the setup. This 15-foot replacement liner is designed to fit Lincoln Magnum® PRO AL Pistol Grip push-pull MIG guns, providing a smooth, consistent conduit for your wire. By minimizing friction and drag, it helps prevent the frustrating feeding issues—such as bird-nesting at the feeder or surging at the arc—that can ruin welds and waste valuable time.

This liner is rated for a wire diameter range of .035" to 1/16", making it a versatile choice for shops that switch between different gauges of aluminum wire. The 15-foot length matches the standard cable length of many push-pull systems, ensuring a perfect fit without the need for trimming or modification in most standard setups. Using genuine Lincoln Electric parts ensures that your equipment operates at peak efficiency. Generic liners may not have the precise internal tolerances required for push-pull systems, leading to slippage or excessive drag on the wire.

Installation is straightforward, allowing operators to swap out old, contaminated, or kinked liners quickly and get back to welding. For aluminum welding, cleanliness is paramount; a dedicated liner prevents cross-contamination from steel shavings that might be present in multi-use liners, which can cause weld defects like porosity and inclusions. By dedicating this liner solely to your aluminum projects, you ensure X-ray quality welds and structural integrity. The KP3543-35116-15 is built to withstand the rigors of daily shop use while maintaining the delicate touch needed for aluminum wire delivery.
