KP2881-15 - Lincoln KP2881-15 Aluminum Conduit Liner for Cougar Guns

Smooth Feeding for Your Aluminum Projects

If you are welding aluminum, you know that feeding the wire is half the battle. The Lincoln Electric KP2881-15 Wire Conduit is your first line of defense against the frustration of bird-nests and erratic arcs. Designed specifically for the Lincoln Cougar™ Pistol Grip Push-Pull Gun, this 15-foot liner is built to handle the unique properties of aluminum wire. Unlike standard steel liners which can be too rough or create too much friction for soft aluminum, this conduit provides a slick, consistent path that lets your wire glide smoothly from the feeder to the contact tip.

This liner is rated for wire sizes ranging from .035" to 1/16", making it a versatile addition to your consumables kit. Whether you are welding thin gauge sheet metal on a boat hull or heavier aluminum sections for a trailer, this conduit ensures your wire delivery stays constant. Consistent wire speed means a consistent arc, better puddle control, and ultimately, a better-looking weld bead. When your equipment fights you, weld quality drops; this liner ensures your Cougar gun works with you, not against you.

Replacing your liner is a standard maintenance task that can drastically improve performance. Over time, liners accumulate aluminum shavings and dust, which increases drag and strains your gun's drive motors. Swapping in a fresh KP2881-15 restores that factory-fresh feel to your gun's feeding action. It is a simple upgrade that pays for itself by preventing burn-backs and the wasted time spent clearing jams.

Don't compromise your aluminum welds with a dirty or incorrect liner. Stick with genuine Lincoln Electric parts to ensure your Cougar gun performs exactly as it was engineered to. The KP2881-15 offers the durability and precision fit you need to keep your arc lit and your production moving. Keep a spare on the shelf so you are never stuck waiting on parts when a big aluminum job lands in your shop.
