Drive Roll Kit for Flux-Cored Wire
This Lincoln Electric K2403-2 kit supplies two V-knurl drive rolls sized for .035 in flux-cored wire. It fits Power MIG 216, 256 and 350MP welders as well as models K2403-2, K2816-2, K3068-1, K4023-1 and K4023-2. Welders running flux-cored processes on these machines use the kit to maintain consistent wire feed. Buyers who need solid-wire drive rolls or a different wire diameter cannot use this kit.
Two V-Knurl Rolls Included
The package contains exactly two drive rolls with a V-knurl profile designed for flux-cored wire up to .035 in. No additional guides, tension springs or software are supplied. The knurl geometry replaces the factory rolls to reduce slipping on tubular wire. Operators who expect a complete wire-feeder overhaul or extra consumables will not find them here.
Direct Replacement Installation
Each roll slides onto the existing drive shafts of the compatible Power MIG and listed model feeders without tools. The V-knurl profile must match the wire type; using it with solid wire causes feeding errors. Misidentifying the welder series or wire diameter is the most common reason the rolls do not engage correctly.

Questions about this item
How often will I need to replace the two V-knurl drive rolls when running flux-cored .035 in wire?
The kit contains two V-knurl drive rolls sized for .035 in flux-cored wire; replacement interval depends on your wire feed volume and the abrasiveness of the specific filler metal you use.
What component limits continuous feeding first during long flux-cored runs?
The V-knurl drive rolls gripping the .035 in flux-cored wire are the first wear point; as the knurl profile flattens, feed consistency drops before the drive motor or tensioner reaches its limit.
How much extra heat or noise do the drive rolls add when the welder runs all day?
The drive rolls themselves generate minimal additional heat or noise; any sustained temperature rise or sound comes from the welder’s wire feeder motor and gearbox, not from the rolls.
