48H365 - Walter Surfox 204 Replacement Control Board and Panel

Restore Precision to Your Surfox System

The Walter Control Panel Assembly (48H365) is the definitive OEM replacement component designed specifically for the Surfox 204 electrochemical weld cleaning system. In the demanding field of industrial metal finishing, the Surfox 204 is a workhorse, utilizing electrochemical technology to clean, passivate, and polish stainless steel welds. The control panel serves as the central nervous system of this unit, regulating the precise delivery of current and electrolyte fluid to the workpiece. Over time, exposure to harsh shop environments, accidental impacts, or heavy repetitive use can degrade the responsiveness of the interface buttons or the internal electronics of the panel.

This assembly (Part No. 48-H-365) is not merely a cosmetic faceplate but a fully integrated control unit. It manages the critical switching between AC mode (for cleaning and marking) and DC mode (for polishing and etching), ensuring the operator has full command over the finish quality. Furthermore, it houses the logic for the electrolyte pump system, allowing users to toggle between manual flow, automatic flow, or variable settings depending on the application requirements. Using non-OEM parts for such critical regulation can lead to inconsistent voltage outputs, potentially damaging the workpiece or the internal transformer of the machine.

Installation of the 48H365 is straightforward, designed to fit the chassis of the Surfox 204 perfectly. The ribbon cables and connectors are pre-configured to mate with the machine's internal power supply and pump harness, minimizing downtime during repair. By replacing a faulty control panel with this genuine Walter part, you ensure that the safety interlocks, current limiters, and variable power settings function exactly as the manufacturer intended. This component is essential for maintenance teams looking to extend the service life of their existing capital equipment rather than investing in entirely new systems.

Key Technical Functions:

• Mode Regulation: Switches internal circuitry between cleaning (AC) and polishing (DC) outputs.


• Pump Management: Controls the peristaltic pump speed and activation for consistent electrolyte delivery.


• User Interface: Provides tactile feedback and visual LED indication of machine status.
