0369557004 - ESAB 1.2-1.6mm Knurled Drive Roll for Flux-Cored Wire

Optimize Your Flux-Cored Welding with ESAB 0369557004

For professional welders demanding precision and reliability, the ESAB Feed Roll 1.2-1.6mm Knurled (0369557004) is the definitive solution for feeding tubular welding wires. This drive roll is specifically engineered to handle the unique challenges associated with flux-cored (FCAW) and metal-cored (MCAW) welding processes. Proper drive roll selection is paramount to maintaining a stable arc, and this knurled roller delivers the positive grip necessary for consistent wire delivery.

The 0369557004 features a dual-size configuration suitable for 1.2mm (0.045 inch) and 1.6mm (1/16 inch) wires. The knurled groove design provides mechanical traction by gripping the surface of the wire. This allows the wire feeder to push the wire through the liner and gun cable with minimal drive roll tension. Reducing tension is crucial when welding with cored wires, as they are essentially hollow tubes filled with flux or metal powder. High tension with a smooth groove roll would flatten the wire, causing it to drag in the contact tip and resulting in poor electrical conductivity and arc instability.

Technical Specifications and Compatibility

Manufactured to ESAB's exacting standards, this feed roll is compatible with a wide array of ESAB wire feed units, including the Origo Feed and Aristo Feed lines. The roll is crafted from high-grade tool steel and heat-treated to withstand the abrasive nature of welding wire, ensuring a long service life. The precision machining ensures that the roll runs true, minimizing vibration and wear on the feeder motor bearings.

Key Benefits:

• Positive Traction: The serrated teeth of the knurled groove prevent slippage, ensuring the wire feed speed matches the set parameters exactly.
• Wire Integrity: Allows for lower tension arm pressure, preventing the deformation of tubular wires.
• Versatility: One roll handles two of the most common heavy-industrial wire diameters.

Regular inspection of your drive rolls is a critical maintenance task. If you notice metal shavings accumulating in the feeder mechanism or experience erratic wire feeding despite a clean liner, it may be time to replace your drive rolls. Installing the ESAB 0369557004 is a quick and effective way to revitalize your wire feeding system and ensure your welds remain defect-free.
