994160 - ESAB MIG-31 Wire Feeder Pressure Roller Assembly

Precision Wire Control for MIG-31 Feeders

For professional welders, arc stability is everything, and it starts at the wire feeder. The ESAB Pressure Roll (SKU: 994160) is the dedicated idler component for the MIG-31 wire feed assembly. This roll acts as the counter-pressure to the drive roll, sandwiching the welding wire to generate the friction necessary to push it through the liner and out the contact tip. If your pressure roll is worn, grooved, or not spinning freely, you will experience micro-stoppages or speed fluctuations that result in burn-backs, sputtering, and inconsistent bead profiles.

This assembly is engineered to apply uniform pressure across the wire surface. This is particularly important when working with softer wires like aluminum or flux-cored wires that can be crushed if the tensioning geometry is incorrect. The ESAB 994160 maintains the correct alignment and pressure distribution, ensuring that the drive rolls can do their job without slipping. It is a direct replacement part, meaning no modifications are required for installation—simply remove the old assembly and secure the new one in place.

Don't let a small mechanical component compromise your weld integrity. Symptoms of a failing pressure roll often mimic other issues, such as a bad liner or contact tip. If you have ruled those out and still experience feed issues on your MIG-31 unit, inspecting and replacing the pressure roll is the next logical step. Keep your ESAB equipment running at peak performance with this genuine replacement part.
