KP2118-2 - Lincoln Electric KP2118-2 Outgoing Guide Tube Insert for .045-.052 Wire

Keep Your Wire Running Smooth and Steady

There is nothing more frustrating than being in the middle of a long weld and feeling the wire start to stutter. You check your contact tip, you check your liner, but the problem persists. Often, the culprit is a worn-out guide tube in your feeder. The Lincoln Electric KP2118-2 Guide Tube Insert is the simple fix you need to get back to laying smooth beads. Designed specifically for .045 to .052 inch (1.2-1.3 mm) wire, this outgoing guide tube sits right after your drive rolls, making sure the wire shoots straight into the gun cable without kinking or wandering.

Think of the guide tube as the steering wheel for your welding wire. If it's worn out or grooved, the wire can slip sideways, causing erratic feeding and that dreaded burn-back. This "Outgoing" insert is built tough to handle the constant friction of steel, stainless, or flux-cored wires sliding through it all day long. It bridges the gap between the power of your drive motor and the start of your gun liner. By keeping this gap tight and aligned, the KP2118-2 prevents the wire from buckling—saving you from the headache of opening up the feeder to cut out a birdnest of tangled wire.

Installation is a breeze. It's a direct replacement for the stock part in your Lincoln feeder, meaning you don't have to fight to get it to fit. We recommend keeping a few of these in your shop toolbox. They are small, affordable parts that make a massive difference in how your machine feels. When you switch wire sizes or notice your feeding getting sloppy, pop in a fresh KP2118-2. It’s cheap insurance against downtime. Whether you are fabricating structural steel or running heavy equipment repairs, reliable wire feeding is the key to productivity. Don't let a $20 part cost you hours of work—stick with genuine Lincoln Electric parts and keep your arc lit.
