48H325 - Walter Surfox 104 Replacement Main Circuit Board

Restore Precision to Your Surfox System

The Walter 48H325 PCB Assembly is the critical central processing unit designed specifically for the Surfox 104 electrochemical weld cleaning system. As the brain of the machine, this printed circuit board (PCB) manages the complex interplay between electrical output and electrolyte fluid delivery, ensuring that your stainless steel cleaning operations remain consistent, safe, and effective. When a control board fails, it can lead to erratic power delivery, pump failure, or a complete system shutdown, halting production and compromising finish quality.

Manufactured directly by Walter Surface Technologies, this OEM replacement part guarantees perfect compatibility with the Surfox 104's internal architecture. Unlike generic electrical components, the 48H325 is calibrated to handle the specific voltage requirements and duty cycles of electrochemical cleaning. It precisely regulates the current sent to the cleaning wand, allowing for the seamless removal of heat tint and discoloration without altering the parent material's surface. Furthermore, it controls the integrated pump system, ensuring the correct flow rate of electrolyte solution to the tip, which is vital for preventing overheating and ensuring passivation.

Industrial environments are harsh on electronics, and while Surfox machines are built to last, the main board can eventually succumb to wear, electrical surges, or accidental damage. Replacing the board with a genuine 48H325 ensures that all safety features, including thermal overload protection and low-fluid sensors, function exactly as intended. This component is essential for maintenance teams looking to extend the service life of their capital equipment rather than investing in entirely new units.

Technical Integrity and Safety

Using genuine Walter parts maintains the CE and UL compliance of your equipment. The 48H325 board is built with high-quality capacitors, resistors, and logic chips designed to withstand the inductive loads typical of welding and cleaning environments. Installation restores the machine's ability to switch between modes (AC/DC where applicable on specific models) and manage variable power settings, ensuring that operators have the fine control needed for delicate work or heavy-duty cleaning.
