KP1899-1 - Drive Roll and Guide Tube Kit for Solid Wire (3/32 - 7/32 Inch)

Smooth Feeding for Heavy-Duty Welding

Keep your Lincoln Electric wire feeder running like new with the KP1899-1 Drive Roll and Guide Tube Kit. If you are running heavy solid wire between 3/32" and 7/32", you know that feeding issues can stop a job in its tracks. Whether you are operating an NA-3S, NA-4, NA-5, or a Cruiser tractor system, this kit is the exact replacement you need to ensure your wire feeds consistently, arc after arc. There is nothing worse than fighting a feeder that slips or jams when you are in the middle of a critical pass.

This kit isn't just a spare part; it's an upgrade to your peace of mind. It includes a precision-machined drive roll designed to grip solid wire firmly without crushing it, alongside a perfectly matched guide tube. The guide tube is critical because it aligns the wire exactly where it needs to go as it leaves the rolls, preventing the wire from wandering or scraping against the feeder housing. When you are pushing large diameter wire, that alignment is key to preventing drag and ensuring the wire hits the contact tip smoothly.

Designed specifically for solid wire applications, this kit handles the unique challenges of feeding stiffer, heavier wires used in structural and heavy fabrication work. Worn drive rolls often cause erratic feeding, which looks like a voltage issue at the arc but is actually a mechanical problem back at the feeder. By swapping out your old, grooved rolls with this fresh kit, you eliminate variables in your welding setup. You get a stable arc, consistent penetration, and less spatter caused by irregular wire speeds.

Installation is straightforward, getting you back to welding quickly. Because it is a genuine Lincoln Electric product, you don't have to worry about fitment issues or poor quality materials that wear out in a week. This kit is built to handle the heat and the workload of a professional shop. Don't let worn consumables compromise your weld quality. Keep a KP1899-1 kit on hand for your NA-series feeders and ensure your heavy wire applications run as smoothly as possible.
