0445850004 - ESAB V-Groove Drive Roll 1.0mm / 1.2mm for Solid Wire

Reliable Wire Feeding with ESAB V-Groove Rollers

Ensure your ESAB welding equipment operates at peak performance with the genuine ESAB Feed Roller V 1.0/1.2 (Part Number 0445850004). Designed specifically for professional fabrication environments, this feed roller is an essential component for maintaining a stable and consistent welding arc. The roller features a precision-machined V-groove geometry, which is the industry standard for feeding solid "hard" wires such as mild steel and stainless steel. Unlike knurled rollers that bite into the wire, the smooth V-groove provides excellent traction through surface contact friction without deforming the wire's cross-section or flaking off copper coating, which can clog liners.

This versatile drive roll is engineered with a dual-groove design, allowing welders to switch between 1.0mm (0.040") and 1.2mm (0.045") wire diameters simply by reversing the roller. This flexibility is ideal for shops that frequently change wire sizes for different material thicknesses, reducing the need to keep multiple single-size rollers in inventory. Manufactured from high-grade hardened steel, the ESAB 0445850004 is built to withstand the rigors of industrial use, resisting wear and maintaining its dimensional accuracy over long periods of operation.

Proper wire feeding is critical for achieving high-quality welds. A worn or incorrect drive roll can lead to wire slippage, erratic arc characteristics, and the frustrating "burn-back" phenomenon. By replacing your feed rollers regularly with genuine ESAB parts, you ensure that the wire is delivered to the contact tip smoothly and at a constant speed. This specific roller is compatible with a range of ESAB wire feeders and compact MIG machines. Whether you are fabricating structural steel or performing precision stainless work, trust Josef Gas to supply the correct OEM components to keep your production line moving efficiently.

Installation is straightforward and typically requires no special tools, allowing operators to swap rollers quickly during setup changes. Always verify your wire feeder model compatibility and ensure the pressure arm tension is set correctly for the wire size being used to maximize the life of both the roller and the welding liner.
