238888 - Hobart Handler 125 EZ Control Board Assembly 238888

Restore Your Welder's Brain

The Miller 238888 Circuit Card Assembly is the central nervous system for your Hobart Handler 125 EZ. If your welder has stopped feeding wire consistently, or if the arc has become erratic and uncontrollable, the main control board is often the culprit. As an electronic component exposed to the harsh environment of a workshop—dust, vibration, and thermal cycling—circuit boards can eventually fail. This genuine OEM replacement part is designed specifically by the manufacturer to restore your machine to its original operating specifications.

Using genuine parts like the 238888 ensures that the calibration for wire speed tracking and voltage output remains accurate. Generic or repaired boards often lack the precise tuning required for the "EZ" single-knob control system that makes the Handler 125 EZ so user-friendly. By swapping out a faulty board with this factory-fresh unit, you eliminate the frustration of troubleshooting intermittent electrical gremlins and get back to welding.

Installation involves accessing the internal electronics bay of the welder. While this is a technical repair, the board is designed with specific connection points that match your machine's wiring harness. Please ensure the machine is unplugged and capacitors are discharged before attempting any internal repairs. This board is the direct successor to previous part revisions, incorporating any manufacturing updates for improved reliability.
