999324 - ESAB 3/32 U-Groove Drive Roll Kit 1-1/2 OD

Precision Wire Feeding for Soft Alloys

The ESAB 999324 Feed Roll Kit is a specialized component engineered to facilitate the smooth transport of 3/32-inch (2.4mm) welding wire within compatible industrial wire feeder systems. Featuring a 1-1/2 inch outer diameter, these rolls are machined with a distinct U-groove profile. Unlike standard V-groove rolls designed for hard steel wires, the U-groove geometry provides a larger contact surface area that gently grips soft wires, such as aluminum, without biting into the surface or causing cross-sectional deformation.

Maintaining the structural integrity of the wire is critical in high-amperage MIG welding applications. Deformation caused by improper drive roll selection can lead to poor electrical contact at the contact tip, arc instability, and increased wear on liner components due to shaving. This kit is manufactured to strict OEM tolerances, ensuring concentricity and balance, which minimizes vibration and motor load during operation. It is an essential component for fabricators requiring high-quality aluminum welds.

The kit typically includes the necessary rolls to configure the drive stand for 3/32-inch wire. The hardened steel construction ensures durability even in high-duty cycle environments. By using genuine ESAB parts, operators ensure that the wire feed mechanism operates at peak efficiency, reducing downtime associated with feed failures and liner clogging.
