0671164080 - ESAB A2 Wire Reel Hub Assembly

Technical Overview of the ESAB A2 Wire Reel Assembly

The ESAB 0671164080 Wire Reel is a critical mechanical sub-assembly designed specifically for the A2 series of automatic welding tractors and heads, including the A2 Multitrac and A2 Tripletrac systems. In automated Submerged Arc Welding (SAW) and heavy-duty MIG/MAG applications, consistent wire tension is paramount to process stability. This reel assembly acts not merely as a holder for the wire spool but as a tensioning device that integrates a braking mechanism to manage the inertia of heavy wire coils.

Constructed to ESAB's rigorous OEM specifications, this component ensures that the wire feeds smoothly into the drive rolls without overrunning when the motor stops. The integrated brake hub allows operators to fine-tune the drag on the spool, compensating for the decreasing diameter of the wire coil as it is consumed. This precise control is essential for preventing "bird-nesting" or tangling at the inlet guide, which can cause significant downtime in automated environments. The assembly is engineered to withstand the mechanical stresses and environmental conditions typical of heavy fabrication and shipyard welding.

Installation of the 0671164080 is straightforward, designed to mount directly onto the A2 carrier frame. It supports standard industrial wire spool dimensions used in automation. By utilizing genuine ESAB replacement parts, facilities maintain the integrity of their welding systems, ensuring that the interaction between the wire feeder control loop and the physical wire supply remains linear and predictable.
