0558102378 - ESAB U-Groove Drive Roll Set for Aluminum Wire (5/64" & 3/32")

Precision Wire Feeding for Soft Alloys

The ESAB 0558102378 Feed Roll Set is a critical component for industrial wire feeding systems, specifically engineered to handle the unique rheological properties of soft welding wires such as aluminum. Unlike standard V-groove rolls which apply point-pressure that can deform or shave soft wires, these rolls feature a precision-machined U-groove profile. This geometry increases the surface area of contact between the drive roll and the wire, allowing for effective traction force transmission without compromising the wire's cross-sectional integrity. This is essential for maintaining consistent electrical contact at the contact tip and ensuring a stable arc.

Designed to accommodate wire diameters of 5/64" (approx. 2.0mm) and 3/32" (approx. 2.4mm), this set provides versatility for heavy-duty fabrication tasks. The manufacturing tolerances of these genuine ESAB parts ensure perfect concentricity and alignment within the wire feeder mechanism. Misalignment in drive systems is a leading cause of feed issues; by utilizing OEM specifications, this set guarantees optimal interplay with the pressure rolls and wire guides. The hardened steel construction offers resistance to wear, maintaining the groove profile over extended periods of high-volume production.

In automated and semi-automated welding environments, the reliability of the wire feed system is paramount. Slippage or wire deformation can lead to burn-backs, erratic arc characteristics, and costly downtime. By employing the correct U-groove drive rolls, operators can ensure that the wire delivery speed matches the commanded feed rate accurately. This set of two rolls is designed for immediate integration into compatible ESAB wire feeders, restoring factory-level performance to your equipment.
