36868 - MT-250 SG Spool Gun Pressure Roller

Product Overview

The ESAB 36868 Pressure Roll is a specialized replacement component engineered for the MT-250 SG Spool Gun. As a critical element of the wire drive mechanism, this pressure roll functions as the idler interface, applying controlled force against the welding wire to ensure it engages correctly with the drive roll. Proper tension is essential for consistent arc stability and weld quality, particularly in spool gun applications where softer wires like aluminum are frequently used.

Over time, pressure rolls can develop flat spots, wear down, or seize, leading to erratic feeding, wire slippage, or birdnesting. This genuine ESAB part (SKU 36868) is manufactured to precise tolerances to restore the original feeding characteristics of the MT-250 SG system. It is designed for straightforward installation during routine maintenance or repair cycles.

Technical Compatibility

This component is specifically validated for use with the MT-250 SG series. It works in conjunction with the gun's tension arm assembly to maintain the delicate balance required to feed wire without deforming it. Using genuine OEM parts ensures that the dimensional accuracy matches the gun housing and drive assembly, preventing mechanical binding and ensuring smooth operation.
