OVERVIEW

Reliable Wire Feeding with Esab OEM Parts

The Esab 999332 Drive Roll Kit is an essential component for professional welders utilizing 1/16-inch (1.6mm) flux-cored or metal-cored wires. Designed specifically for ESAB's robust 4-roll wire feed systems, this kit ensures that your welding operations run smoothly and efficiently. In the world of industrial welding, the consistency of wire delivery is paramount; even minor slippage can lead to arc instability, burn-backs, and downtime. By choosing genuine ESAB parts, you guarantee compatibility and performance that matches the original specifications of your machine.

Optimized for Cored Wires

Unlike solid wires, flux-cored and metal-cored wires have a tubular construction that can be susceptible to crushing if improper drive rolls are used. The Esab 999332 features a knurled groove design. This textured surface bites gently into the wire's surface, providing positive traction without requiring excessive tension from the pressure arm. This "teeth-like" grip allows the feeder to push the wire through long gun cables and torch liners with ease, maintaining a constant wire feed speed even in demanding positions.

Compatibility and Durability

This drive roll kit is engineered to fit a wide range of ESAB's heavy-duty feeders, including the legendary MigMaster 250/251/300i series, MobileMaster units, and select Aristo wire feeders. The rolls are manufactured from hardened steel to resist wear caused by the abrasive nature of knurled feeding and the friction of the wire. Whether you are fabricating structural steel or performing heavy equipment repair, installing fresh drive rolls is a simple maintenance step that yields significant improvements in weld quality.

Key Benefits

  • Positive Grip: Knurled texture prevents slipping on tubular wires.
  • Reduced Deformation: Feeds wire without crushing the flux core.
  • OEM Precision: Guaranteed fit for specified ESAB 4-roll systems.
  • Long Life: Heat-treated steel construction resists grooving and wear.

FAQ

This kit is designed specifically for 1/16 inch (1.6 mm) diameter welding wire.

It is not recommended. These rolls have a knurled (serrated) groove which is designed for cored wires. Using them on solid wire can shave the copper coating, creating debris that clogs liners, and may deform the wire surface.

This kit fits a range of ESAB 4-roll feeders, including the MigMaster 250, 251, 300i, MobileMaster 2, Dip Pak 250, and select Aristo wire feeders.

Flux-cored wire is tubular and softer than solid wire. Knurled rolls provide grip (traction) without needing excessive clamping pressure, which prevents crushing or deforming the hollow wire.

Yes, this is a genuine OEM Esab part, number 999332.

Inspect the knurling (teeth) in the groove. If they appear smoothed out or filled with debris, or if you experience wire slippage despite correct tension, it is time to replace the rolls.

No, for aluminum wire you should use U-groove drive rolls to prevent shaving the soft aluminum. Knurled rolls are too aggressive for aluminum.

This kit is designated for 4-roll systems, which are common on the heavy-duty industrial feeders listed in the compatibility section.
