Drive Roll Kit for Power MIG Welders

This Lincoln Electric drive roll kit contains two V-groove rolls designed for solid wire up to .04 in diameter. It fits Power MIG 216, 256 and 350MP welders as well as the listed wire feeder models. The kit replaces worn rolls to restore consistent wire feeding.

Sustained Feeding Performance

The V-groove profile maintains positive contact with solid wire during long welding passes, reducing slip that can cause erratic arcs. Two rolls share the drive load evenly, so heat build-up in the drive system stays low even on extended jobs. Regular roll changes keep feed speed accurate over time.

Maximum Wire Diameter .04 in

The .04 in limit is the single specification that determines compatibility; wire thicker than this will not track in the grooves and will jam. Shops running larger diameters need a different roll kit. Buyers using flux-cored or aluminium wire should select the appropriate groove type instead.

Questions about this item

Will the .04 in drive rolls generate extra heat or noise when the Power MIG 216 runs all day?

The V-groove rolls are passive metal parts; they add no motor load, fan noise or measurable heat to the welder during continuous operation.

Which Lincoln wire feeder models must I already own for the K2403-2 kit to fit?

Compatible feeders include K2327-4, K2327-5, K2327-6, K2327-7, K2536-4, K2536-5, K2613-5, K2614-5, K2614-6, K2999-1, K3289-1, K4101-1, K4101-2, K4266-1, K4266-2, K4266-3, K4267-2, K4267-3, K4267-4 and K4267-5.

Can I keep my older Power MIG 256 and just swap in these .04 in rolls for solid wire?

Yes, the kit is listed for the Power MIG 256 and other series models; replacing the existing rolls with this two-roll V-groove set lets you run .04 in solid wire.
