MIG Consumable Kits

Lincoln Electric MIG Consumable Kits — Drive Rolls, Wire Guides, and Setup Packages

A MIG welding system is only as reliable as the consumables keeping wire moving through it. Lincoln Electric MIG consumable kits package the parts your wire feeder and MIG gun depend on — drive rolls, guide tubes, contact tips, and wire guides — into matched sets engineered for specific wire diameters, feeder models, and wire types. Whether you're setting up a new machine, converting a feeder from solid to flux-cored wire, or replacing worn drive rolls on a high-duty-cycle production setup, the right kit eliminates guesswork and gets your system back in spec immediately.

WeldingMart stocks the full Lincoln Electric kit catalog, including drive roll kits for the SP-255, WM-255, HELIX SF70A/SF70C, Tiny Twin, and HyperFill feeders, plus welding kits for Innershield and aluminum wire setups. Orders placed before 3 PM CT ship same day. Free freight on orders over $99.

Kit Types in This Collection

Drive Roll Kits

Drive roll kits are the most ordered Lincoln consumable kits. Each kit includes matched drive roll pairs (and guide tubes where required) sized for a specific wire diameter and wire type. Lincoln's drive roll system uses V-groove rolls for solid and most cored wires, U-groove rolls for aluminum wire, and knurled rolls for flux-cored and metal-cored wires that need extra grip.

Selecting the right kit requires three inputs: your feeder model, your wire diameter, and your wire type. Common KP-prefix kits cover the KP653, KP654, KP655, KP1505, KP1696, KP1697, KP4335, and KP4388 series — each engineered for specific Lincoln feeder platforms. The Drive Roll/Guides/Tips kits in the Tiny Twin series (KP1901 family) go further, bundling drive rolls with guide tubes and contact tips in one package for submerged arc and heavy-gauge applications.

Wire diameters covered range from .023 in through 7/64 in (0.6–2.8 mm), including fractional sizes for aluminum (.035A, 3/64A, 1/16A) and cored wires in every standard gauge. HELIX SF70A/SF70C kits add aluminum-capable U-groove rolls for the onboard feeder used in Lincoln's robotic and semi-automatic cell systems.

Wire Setup and Conversion Kits

Beyond individual drive roll replacements, Lincoln packages complete setup kits for specific wire and application types. Innershield Welding Kits (K549, K2528, K3281 series) include all the feeder components needed to run self-shielded flux-cored wire — drive rolls, guide tubes, and associated hardware sized for a specific wire diameter. Aluminum Welding Kits (K663, K664 series) provide U-groove rolls and the liner/guide components aluminum wire requires to feed without shaving.

MIG Conversion Kits (K610, K2526) configure select multi-process machines — including the Lincoln Power MIG and Weld-Pak series — to run solid MIG wire where the machine shipped with a different process configuration. The HyperFill MC kit extends the HyperFill system to metal-cored wire, and the SP-255/WM-255 kits bundle cored or solid drive rolls for Lincoln's portable feeders used in shipbuilding and field fabrication.

Feeder Accessory Kits

Several specialty kits address specific feeder system needs: the Feeder Insulator Kit (100ID) provides electrical insulation hardware for Lincoln's wire drive assemblies; the Transformer Kit 42V (K1520-1) configures select feeders for 42-volt operation in safety-voltage environments; and the Deluxe Adjustable Gas Regulator and Hose Kit (K586-1) pairs a precision adjustable regulator with a matched hose for shielding gas delivery setup on new MIG or flux-cored installations.

How to Select the Right Drive Roll Kit

Correct drive roll selection is the single most common source of wire feed problems. An undersized bore damages wire surface finish; an oversized groove loses grip and causes slip-feed. Follow these four steps before ordering:

1. Confirm feeder model. Lincoln drive roll kits are designed for specific feeder platforms. The KP prefix and series number encode both the roll geometry and the feeder body it fits. Identify your feeder model number from the nameplate before selecting a kit.
2. Match wire diameter exactly. Drive roll bore size is specified in the kit title. The diameter in the title refers to the nominal wire size the roll is designed to feed — not a range. For borderline sizes (e.g., .045 vs. .047), use the kit sized for your actual wire's nominal diameter.
3. Choose the correct roll type for wire type. V-groove rolls for solid wire and most cored wires. U-groove rolls for aluminum wire. Knurled rolls for flux-cored, metal-cored, and other wires that require enhanced grip. Knurled rolls on solid wire will damage the wire surface and contaminate the weld; V-groove on flux-cored wire will slip under load.
4. Check kit contents against your requirement. Some kits include drive rolls only; others include guide tubes, contact tips, or guide bushings. Read the product title and description to confirm the kit contents match what your feeder needs for a complete replacement.

Feeder Platform Compatibility Reference

Lincoln Electric's drive roll kits are not cross-compatible between feeder generations. Use this reference to identify the correct kit series for common Lincoln platforms:

• SP-255 / WM-255 feeders: KP674 series (solid, cored, aluminum — select by wire type and diameter)
• LN-7, LN-8, LN-9, LN-25 feeders: KP653, KP655, KP1505 series (full size range .023–7/64)
• Power Feed / Power MIG feeders: KP1505, KP1696, KP1697 series
• HyperFill 2-roll feeder: KP4388 series (knurled .045 for metal-cored)
• HELIX SF70A/SF70C onboard feeder: KP52079 series (.052 and .062, solid and aluminum)
• Tiny Twin (submerged arc / heavy-gauge MIG): KP1901 series (includes guide tubes and tips)
• Wire Wizard / KP4335 series: V-groove and U-groove rolls for cored, solid, aluminum across .035–.047 range

Why Kit Replacement Beats Individual Parts Ordering

Drive rolls and guide tubes wear together. Replacing only the roll and leaving a worn guide tube in place re-creates the same wire feed resistance within a fraction of the new roll's service life. Lincoln kits are engineered as matched sets — the roll geometry, bore diameter, and guide tube inner diameter are spec'd together to deliver consistent wire tracking from feeder inlet to drive roll exit.

Kit ordering also eliminates the risk of mixing part generations. Lincoln has revised several drive roll series over production runs; a roll from one generation may not mate cleanly with a guide tube from another. Kits ship as a verified compatible set, which is the fastest way to restore a feeder to factory wire-feed performance and avoid repeat service calls.
