KP545-3/32 - Lincoln Electric KP545-3/32 Drive Roll & Guide Tube Kit for LN9/NA-5R

Reliable Feeding for Heavy-Duty Welding

When you are welding thick materials with heavy-gauge wire, the consistency of your wire feed is just as important as your voltage settings. The Lincoln Electric KP545-3/32 Drive Roll Kit is the essential upgrade for your LN9 GMA or NA-5R wire feeder, specifically tailored for running .068 to 3/32 inch (1.7-2.4 mm) wire. Whether you are running solid wire for structural work or flux-cored wire for deep penetration, this kit ensures your machine delivers wire smoothly and reliably, hour after hour.

Wire slippage is the enemy of productivity. It leads to burn-backs, erratic arcs, and frustrating stops to fix the feeder. This kit features a 4-roll configuration designed to grip the wire firmly without crushing it. This is especially vital when using cored wires, which have a hollow center and can be easily deformed by improper drive rolls. The 4-roll design spreads the pressure out, giving you positive traction that pushes the wire through long gun cables and around bends without hesitation. This means you can focus on the puddle and the weld quality, rather than worrying about whether the wire is going to stop feeding mid-bead.

Complete Kit for Quick Changeovers

The KP545-3/32 isn't just about the rolls; it's a complete solution. It comes with the specific guide tubes required for this wire size range. Guide tubes are often overlooked, but they are critical for guiding the wire straight into the liner. Using the wrong size guide tube can cause drag or allow the wire to wander, leading to shavings that clog your liner. By installing the matched guide tubes included in this kit, you ensure a clean, low-friction path for your welding wire from the spool to the contact tip.

As a genuine Lincoln Electric product, you can trust the durability and fit of these components. In heavy industrial environments, equipment takes a beating. Using OEM parts like the KP545-3/32 protects your investment in your Lincoln feeder and ensures it performs to factory specifications. Whether you are retrofitting an older machine or setting up a new line for heavy fabrication, this drive roll kit provides the performance assurance professional welders demand.
