0445850005 - ESAB V-Groove Drive Roll 1.2mm for Solid Wire

Smooth Feeding for Superior Welds

Every welder knows that a stable arc starts with consistent wire feeding. If you are experiencing stuttering, burn-backs, or irregular wire speeds, your drive rolls might be the culprit. The ESAB 0445850005 Feed Roller is designed to restore the smooth, reliable performance of your MIG welder. Specifically engineered for 1.2mm (0.045") solid wires, this V-groove roller provides the perfect amount of traction to push wire through your gun cable without crushing or flattening it. This is crucial because deformed wire can drag inside the liner and wear out contact tips prematurely, leading to frustrating downtime.

Why V-Groove?
V-groove rollers are the correct choice for solid mild steel and stainless steel wires. Unlike knurled rollers which dig into the wire (great for flux-core but bad for solid wire) or U-groove rollers (designed for soft aluminum), the V-groove uses friction and precise geometry to grip hard wires. This ESAB roller is precision-machined to match the 1.2mm wire tolerance exactly, preventing the wire from wandering or slipping under tension.

Built for the Shop
Durability matters in a busy shop. These rollers are made from hardened steel to resist the wear and tear of daily fabrication work. The "1.2 1.2" designation means both slots on the roller are sized for 1.2mm wire, giving you a backup groove ready to go—just flip the roller over when the first side wears out. This simple feature doubles the value of the part and keeps you welding longer.

Maintenance Tip
When installing your new ESAB feed rollers, remember not to overtension the pressure arm. The V-groove is designed to grip without excessive force. Too much tension can strain the motor and deform the wire; too little causes slipping. With a fresh 0445850005 roller, you can set the tension correctly and get back to laying down perfect beads. Keep a spare set in your toolbox so you never get stuck with a feeding issue in the middle of a critical job.
