0334289881 - ESAB A6 Wire Feed Roller Kit 1.6-3.0mm

Precision Wire Feeding for Automated Systems

The ESAB Wire Kit D20 (Part Number 0334289881) is a critical component designed for the maintenance and optimization of ESAB A6 and A2 welding heads. In automated welding processes, particularly Submerged Arc Welding (SAW) and heavy-duty GMAW, the consistency of wire delivery is paramount to achieving defect-free welds. This feed roller kit is engineered to handle a specific range of wire diameters, from 1.6mm to 3.0mm, providing the necessary traction to push heavy solid or flux-cored wires through the liner and contact tip without slippage or deformation.

Manufactured to ESAB's exacting OEM standards, the D20 roller features a hardened surface treatment that resists wear caused by the constant friction of metal-on-metal contact. The geometry of the groove is precisely machined to grip the wire firmly while minimizing the risk of shaving or crushing, which can lead to liner clogging and arc instability. For industrial MRO specialists, using genuine ESAB parts ensures that the mechanical tolerances of the feed unit are maintained, preserving the longevity of the motor and gearbox assembly.

This kit is essential for facilities utilizing ESAB's modular A6 system for beam welding, tank fabrication, or pipe mills. Regular inspection and replacement of the feed rollers are recommended as part of a preventative maintenance schedule. Worn rollers can lead to micro-variations in wire stick-out and voltage, subtly affecting weld penetration and bead profile. By installing the 0334289881 kit, operators ensure that the welding head performs at its rated duty cycle with maximum reliability.
