36461 - ESAB MT-250 SG Spool Gun Spindle Replacement Kit

Restore Precision to Your Aluminum Welding Operations

The ESAB Spindle Kit (36461) is a specialized replacement assembly engineered for the MT-250 SG Spool Gun (Part Number 36779). In industrial fabrication environments, particularly those involving aluminum MIG welding, the spool gun is a workhorse tool. The spindle assembly is the heart of the wire feeding mechanism, responsible for holding the 4-inch wire spool and providing the necessary braking tension to prevent over-spooling. Over time, the friction components and threads of the spindle can wear down due to repetitive spool changes and the vibration inherent in welding operations. This OEM kit provides all the necessary components to completely rebuild the spool holding mechanism, ensuring your equipment operates within factory specifications.

Failure of the spindle mechanism often manifests as inconsistent wire feeding or "bird-nesting," where the wire unspools faster than the drive rolls can feed it. This leads to downtime, wasted consumables, and potential damage to the gun liner. By installing the genuine ESAB 36461 Spindle Kit, maintenance teams can preemptively address these issues. The kit includes the main spindle shaft, the tensioning spring, and the retention hardware, all manufactured to ESAB's rigorous quality standards. This ensures that the braking force applied to the spool is consistent and adjustable, allowing for smooth arc starts and stops without wire overrun.

This component is critical for users of the legacy ESAB Migmaster series who utilize the MT-250 SG for extended reach or soft-wire applications. Maintaining the integrity of the spool gun's mechanical feed system is essential for achieving high-quality welds, particularly when working with soft aluminum grades like 4043 or 5356 which are prone to feeding difficulties. Invest in genuine ESAB parts to extend the service life of your welding assets.
