0445850003 - ESAB 1.0mm V-Groove Drive Roll for Solid Wire

Precision V-Groove Drive Roll for 0.040" Solid Wire

Maximize the performance of your ESAB wire feeder with the ESAB 0445850003 Feed Roller. This specialized drive roll features a V-Groove geometry, the industry standard for feeding solid hard wires such as carbon steel, low-alloy steel, and stainless steel. Designed to accommodate 1.0mm (0.040-inch) wire diameters, this roller is an essential upgrade or replacement for welders demanding precision and reliability in their MIG processes.

Why Choose V-Groove?

The geometry of your drive roll dictates how well the wire is conveyed through the liner to the contact tip. A V-Groove roller creates two points of contact that securely grip the round surface of solid wire. This traction is achieved without biting into the metal or shaving off copper coating, which can clog liners and tips. By maintaining the roundness of the wire, this roller ensures smooth passage through the torch cable, significantly reducing friction and the likelihood of "birdnesting" at the feeder.

Built for Longevity

ESAB manufactures these rollers from robust, hardened steel to withstand the mechanical stress of continuous industrial use. The 0445850003 model is designed with two identical 1.0mm grooves. This reversible design is a practical feature for high-volume shops; once the primary groove shows signs of wear, simply flip the roller to engage the fresh groove. This simple feature extends the service interval and reduces the total cost of ownership for your welding equipment.

Compatibility and Performance

Using the correct drive roll size is non-negotiable for stable arc performance. A roller that is too large will slip, causing the arc to stutter or burn back to the tip. A roller that is too small may crush the wire, leading to feeding drag. This 1.0mm roller is machined to tight tolerances to match 0.040" wire perfectly. It is compatible with various ESAB wire feed units (check your machine's manual for specific fitment). Invest in genuine ESAB consumables to ensure your machine delivers the smooth, spatter-free welding arc it was designed to produce.
