36867 - ESAB MT250SG Steel Drive Roll .023-3/64

Technical Overview of the ESAB 36867 Feed Roll

The ESAB 36867 is a specialized feed roll component engineered for the MT250SG series spool guns. This component is critical for the mechanical transport of welding wire from the spool through the gun liner to the contact tip. Specifically manufactured to handle steel wires, this roll features groove geometry optimized to grip solid steel wire without causing deformation or excessive shaving, which can lead to liner clogging.

The dimensional specifications of this feed roll allow it to accommodate a wire diameter range starting at 0.023 inches (approximately 0.6 mm) up to 3/64 inches (approximately 1.2 mm). This versatility makes it an essential component for fabricators switching between light-gauge sheet metal work and heavier structural repairs using the same spool gun platform. The roll is machined from hardened steel to withstand the abrasive nature of steel welding wires, ensuring a long service life and maintaining consistent feed rates over extended duty cycles.

Proper tensioning and alignment of the feed roll are paramount for arc stability. The ESAB 36867 is designed to fit precisely onto the drive shaft of the MT250SG, eliminating runout that could cause arc wandering. As an OEM part, it adheres to ESAB's strict tolerance standards, ensuring that the gap between the roll and the pressure gear is maintained accurately for the specified wire sizes. This part is identified by the SKU 36867 and is a direct replacement for worn or damaged drive rolls in existing MT250SG setups.

Maintenance professionals should inspect feed rolls regularly for signs of groove wear or debris accumulation. A worn groove can result in wire slippage, leading to burn-back at the contact tip or irregular bead profiles. Replacing the feed roll with this genuine ESAB component restores the mechanical efficiency of the wire feed system, ensuring reliable performance in industrial MIG welding applications.
