0558102375 - ESAB .045" V-Groove Drive Roll Set (2-Pack)

Technical Overview of ESAB 0558102375 Feed Rolls

The ESAB 0558102375 Feed Roll Set is a precision-engineered component designed to facilitate the consistent transport of welding wire within ESAB wire feeding systems. Specifically machined with a V-groove profile, these rolls are optimized for use with .045-inch (1.2mm) solid wires, typically mild steel (ER70S-6) or stainless steel grades. The V-groove geometry is critical for hard wires as it provides two distinct points of contact (per roll) that grip the wire firmly without causing the deformation associated with flat or knurled rolls. Maintaining the roundness of the wire is essential for ensuring good electrical conductivity at the contact tip and preventing accelerated liner wear.

Constructed from high-grade hardened steel, these drive rolls are built to withstand the abrasive friction inherent in continuous industrial welding operations. The hardening process significantly extends the service life of the rolls compared to standard steel components, reducing maintenance intervals and downtime. In a wire feeding system, the drive rolls act as the primary interface between the mechanical motor torque and the consumable wire. Worn or improper rolls can lead to slippage, which results in erratic arc length, burn-back, and inconsistent weld bead profiles. By utilizing this matched set of two rolls, operators ensure balanced traction forces, which is particularly important in 4-roll drive systems where synchronized feeding is required to push wire through long torch cables.

Installation of the 0558102375 set restores the factory-specified feeding performance of compatible ESAB equipment. It is recommended to inspect drive rolls during routine maintenance schedules. Signs of wear, such as a widened groove or rounded edges, indicate a loss of traction capability. Replacing rolls in sets prevents uneven wear patterns and ensures that the wire is fed centrally into the guide tubes. This product is supplied as a package containing two rolls, ready for immediate installation into the wire feed mechanism.
