KP2879-2 - Lincoln Electric KP2879-2 180-Degree Barrel Liner for .035-1/16 Wire

Smooth Feeding for Better Welds

Every welder knows that a smooth wire feed is the secret to a consistent bead. If you are running a 180-degree straight barrel on your Lincoln MIG gun, the KP2879-2 Barrel Liner is the part you need to keep things running right. Designed to handle wire sizes from .035" up to 1/16", this liner sits inside the gun neck and guides the wire straight to the contact tip. Over time, these liners can get clogged with debris or worn down by the wire, leading to friction that causes sputtering and birdnesting.

Swapping out your barrel liner is a quick fix that can solve a lot of frustration. The KP2879-2 is built tough to handle the heat and abrasion of daily welding. Because it is a genuine Lincoln part, you don't have to worry about fitment issues—it slides right into place in compatible 180-degree tubes. This ensures that your wire doesn't drag or snag just before it hits the arc, giving you the control you need for precision work.

Don't let a worn-out liner ruin your welds. Keeping a spare KP2879-2 in your kit ensures you are ready to tackle feeding problems the moment they crop up. Whether you are welding mild steel in the shop or doing heavy fabrication, this liner helps maintain the electrical conductivity and mechanical stability of your wire feed, so you can focus on laying down the perfect bead.
