The ESAB 673305 Gear Hub is a specialized mechanical component designed for the maintenance and repair of ESAB wire feeding systems. In the context of Gas Metal Arc Welding (GMAW) and Flux Cored Arc Welding (FCAW), the consistency of the wire feed speed (WFS) is a paramount variable that directly influences arc stability, deposition rate, and overall weld quality. The gear hub serves as the critical interface between the drive motor's output shaft and the feed rolls, responsible for the transmission of torque and the maintenance of rotational concentricity.
Over time, mechanical wear within the drive assembly can lead to play, misalignment, or stripped engagement points on the hub. These mechanical deficiencies often manifest as irregular wire feeding, slippage under tension, or erratic arc performance that cannot be corrected by adjusting voltage or inductance. The ESAB 673305 is manufactured to strict OEM tolerances, ensuring a seamless fit with compatible ESAB wire feeders. By replacing a worn hub with this genuine component, operators can restore the positive traction required to push welding wire through the liner and contact tip without hesitation or stuttering.
Constructed from high-grade materials capable of withstanding the thermal and mechanical stresses typical of industrial environments, this gear hub is an essential spare for Maintenance, Repair, and Operations (MRO) inventories. It ensures that the drive rolls are seated correctly and rotate true, minimizing runout that could otherwise damage the wire surface or cause premature wear to the feed rolls themselves. For facilities relying on ESAB equipment, utilizing genuine parts like the 673305 ensures equipment longevity and preserves the manufacturer's performance specifications.
Installation of the gear hub should be performed according to the specific service manual for the power source or wire feeder in use. Proper maintenance of the drive system, including the gear hub, is a preventative measure that reduces downtime and rejects caused by feeding issues.
