23612397 - ESAB .035 Upper Pressure Drive Roll Replacement

Precision Wire Feeding Component

The ESAB Upper Pressure Roll (SKU: 23612397) is a critical component in the tribological system of a MIG wire feeder. Designed specifically for use with 0.035-inch (0.9mm) welding wire, this pressure roll applies the necessary normal force against the drive roll to generate friction for wire transport without causing plastic deformation of the wire electrode. Maintaining the correct geometry and surface finish on the pressure roll is essential for achieving a stable laminar flow of wire through the liner and contact tip.

Manufactured from hardened industrial-grade steel, this roll is engineered to withstand the mechanical stresses of continuous industrial welding environments. It features a precision-machined profile that mates perfectly with the corresponding lower drive roll, ensuring the wire remains centered and under constant control. This reduces the likelihood of micro-arcing within the contact tip due to shaving generation or erratic feed speeds.

For maintenance personnel and welding engineers, replacing the pressure roll is a preventative measure that safeguards the consistency of the welding parameters. A worn pressure roll can lead to slippage, which the power source may interpret as a change in arc length or resistance, leading to unstable voltage corrections. Installing the genuine ESAB 23612397 ensures compatibility with the feeder's tensioning arm mechanics and restores the machine to factory specifications.
