KP2173-3 - Lincoln Electric Inner Wire Guide for 1/16 Aluminum Wire (2-Roll System)

Smooth Aluminum Feeding with the KP2173-3

If you have ever welded aluminum, you know the headache of a birdnest. You pull the trigger, the rolls spin, but the wire stops coming out of the tip, and suddenly you have a tangled mess of aluminum spaghetti at the feeder. The Lincoln Electric KP2173-3 Inner Wire Guide is your defense against this frustration. Specifically designed for 1/16-inch aluminum wire running on 2-roll drive systems, this guide is the missing link that keeps your soft aluminum wire moving smoothly from the spool to the puddle.

Why is this specific part so important? Aluminum is soft. If you use a standard steel guide or a guide that is too large, the wire can buckle under the pressure of the drive rolls. The KP2173-3 fits tight to the rolls and supports the wire exactly where it needs it most. It prevents the wire from wandering or kinking before it enters the gun cable. This means you spend less time clearing jams and more time laying down beads. It also prevents the wire from shaving, which keeps your liner clean and your arc consistent.

This is a genuine Lincoln Electric part, meaning it drops right into your compatible 2-roll feeder without modification. Whether you are fabricating aluminum trailers, repairing boat hulls, or working on custom automotive parts, trusting your feed system to the right accessories makes all the difference. Don't let feed issues ruin your weld appearance or slow down your production. Ensure your machine is properly set up for aluminum with the correct inner wire guide.

Installation is straightforward and should be part of your standard changeover process when switching from steel to aluminum or when changing wire diameters. Pair this guide with the correct U-groove drive rolls for the ultimate feeding performance. Keep a spare in your toolbox so you are never caught off guard by a worn guide during a critical job.
