OVERVIEW

Reliable Feeding for Flux-Cored Welding

Tired of your wire slipping or bird-nesting right in the middle of a long weld? If you are running flux-cored or metal-cored wire, the problem might be your drive rolls. The ESAB 37320 Knurled Feed Roll is the solution you need for smooth, uninterrupted wire delivery. Unlike smooth V-groove rolls that rely on friction and high pressure, these knurled rolls have small teeth that grip the wire securely, pushing it through the liner with ease.

This roll is a must-have for welders working with heavier gauge wires. It features a dual-size design, allowing you to run either 1/16" or 5/64" wire with a single accessory. Whether you are fabricating structural steel or repairing heavy equipment, consistent wire feeding is the key to a consistent bead. This genuine ESAB part ensures your machine operates at peak performance.

Why Choose Knurled Rolls?

Tubular wires like flux-core are softer than solid MIG wires. If you tighten a standard smooth roll enough to grip them, you risk crushing the wire into an oval shape. This causes drag in the contact tip and erratic arc issues. The knurled design of the ESAB 37320 allows for positive traction with lighter tension, preserving the round shape of your wire and extending the life of your consumables.

FAQ

This knurled feed roll is specifically designed for tubular wires, such as flux-cored and metal-cored wires. The knurled texture grips the softer wire without crushing it.

It is not recommended. Knurled rolls can dig into solid wire, creating metal shavings that may clog your liner. For solid wire, use a smooth V-groove drive roll.

This is a dual-groove roll that supports 1/16 inch (1.6 mm) and 5/64 inch (2.0 mm) wire diameters.

It fits a variety of ESAB feeders including the MigMaster 250/251/300i, MobileMaster 2, Aristo feeders, and Dip Pak 250.

Simply remove the roll, flip it over to align the desired groove size with the wire path, and reinstall it.

Flux-core wire is hollow and can be crushed by the high tension needed for smooth rolls. Knurled rolls provide traction with less tension, preventing deformation.

Yes, this is a genuine ESAB OEM replacement part, ensuring perfect fit and durability.

This item is typically sold individually. Depending on your feeder (2-roll or 4-roll system), you may need to purchase multiple units.
