W4017013 - Lincoln Electric .045" V-Groove Drive Roll Kit (Set of 2)

Technical Overview

The Lincoln Electric W4017013 is a specialized Drive Roll Kit engineered for industrial wire feeding applications. This set contains two precision-machined rolls featuring a V-Groove profile, specifically calibrated for .045-inch (1.2 mm) solid welding wires. The V-Groove geometry is the industry standard for feeding hard wires such as mild steel and stainless steel, as it provides two points of contact that grip the wire firmly without deforming its cross-section or scraping the copper coating.

Manufactured from high-grade hardened steel, these rolls are designed to withstand the mechanical stress of continuous industrial use. Proper drive roll selection is critical for maintaining arc stability; incorrect groove types or worn rolls can lead to micro-slippages that manifest as erratic arc characteristics. This kit ensures that the wire feeder delivers wire at a constant velocity, matching the power source output for high-quality weld deposition.

Compatibility and Installation

This kit is designed for specific Lincoln Electric wire feeder models that utilize a two-roll drive system or require replacement of both top and bottom rolls. Installation requires verifying the wire diameter matches the stamped indication on the roll face. Users should ensure that the pressure arm tension is adjusted correctly—sufficient to prevent slip, but not so high as to crush the wire, although the V-groove design inherently mitigates crushing risks compared to knurled options.
