0445850032 - ESAB V-K Knurled Drive Roll 1.2mm / 1.4mm

Optimize Your ESAB Feeder Performance

Upgrade or maintain your welding equipment with the ESAB 0445850032 Feed Roller V-K. This precision-engineered drive roll is designed to handle the rigorous demands of flux-cored and metal-cored arc welding (FCAW/MCAW). The roller features a dual-groove configuration supporting 1.2mm and 1.4mm wire sizes, making it a versatile choice for shops that frequently change wire diameters for different material thicknesses. The V-K profile combines a V-groove shape with a knurled texture, specifically engineered to grip softer or tubular wires securely without deforming their cross-section.

Inconsistent wire feeding is a leading cause of welder frustration and downtime. Slippage at the drive rolls can cause the arc to stutter or extinguish, while excessive pressure can flatten cored wires, leading to feeding issues inside the contact tip. The ESAB V-K roller solves this by providing positive mechanical grip, allowing for lower tension settings on the pressure roll. This results in smoother feeding, less wear on the wire feeder motor, and higher quality welds. Made from durable, wear-resistant steel, this roller maintains its dimensional accuracy over long production runs.

Compatible with a range of ESAB wire feed units (check your manual for specific model compatibility, such as Origo Feed or Aristo Feed series), this genuine OEM part guarantees a perfect fit. Keeping a fresh set of drive rolls in your maintenance kit is best practice for any professional welder. When the knurling eventually wears down, replace the rolls immediately to restore optimal traction and arc stability.
