KP2117-1 - Lincoln Electric Outgoing Guide Tube for .030-.035 Wire (MAXtrac)

Stop Birdnesting and Keep Welding

There is nothing more frustrating than being in the middle of a long weld and feeling the wire stutter, only to open your feeder and find a birdnest of tangled wire. Often, the culprit isn't your drive rolls or your liner—it's the guide tube. The Lincoln Electric KP2117-1 is the replacement outgoing guide tube you need if you are running .030 or .035 wire on a Lincoln feeder. This small part does a big job: it catches the wire as it leaves the drive rolls and funnels it smoothly into your gun.

Over time, thousands of feet of wire slide through this tube. Even though it's made of tough steel, it will eventually wear out. A groove can form inside, causing friction that makes your drive rolls slip, or the tip can get burred and shave copper off your wire, clogging up your liner downstream. If you are noticing erratic feeding, sputtering arcs, or if your wire seems to be dragging, check your guide tubes. If you see wear, swap it out with a fresh KP2117-1. It’s a cheap insurance policy against downtime.

This kit is designed for the "Outgoing" side—that means it sits between the drive rolls and the place where you plug in your MIG gun. It is specifically sized for .030" and .035" wire. Using a tube that is too big (like one meant for 1/16" wire) won't support the wire enough, leading to tangles. Using one that is too small will cause drag. This OEM part fits perfectly in Lincoln MAXtrac wire drives, which are found on popular feeders like the LN-25 PRO and LF-72. Installation is usually tool-free or requires just a simple set screw adjustment.

Don't let a worn $20 part cost you hours of production. Keep a spare KP2117-1 in your toolbox or consumables locker. Whether you are in a fab shop, doing automotive repair, or working out of a truck, smooth wire feeding is the key to a good day's work. Trust genuine Lincoln Electric parts to keep your arc steady and your beads looking right.
