48D803 - Walter SURFOX Standard Straight Wand

Optimized Conductivity for Electrochemical Cleaning

The Walter Surface Technologies 48D803 Multifunctional Probe is a critical component of the SURFOX electrochemical weld cleaning system. Engineered to deliver precise electrical current and electrolyte flow to the workpiece, this straight probe serves as the primary interface for cleaning and passivating stainless steel welds. The unit is constructed with a high-conductivity core that minimizes resistance, ensuring that the full power of the SURFOX machine is utilized to remove heat tint and oxidation effectively. The outer body is encased in a durable, chemical-resistant polymer that protects the operator from electrical current and withstands the corrosive nature of phosphoric-acid-based electrolytes used in the process.

Designed for industrial environments, the 48D803 probe features a robust threaded tip that accepts a wide variety of SURFOX accessories, including standard cleaning pads and boots. This modularity allows the operator to adapt the tool to different weld geometries without changing the entire wand. The straight configuration is particularly effective for accessing open surface welds, outer corners, and lap joints where a direct angle of attack is preferred. By maintaining a consistent electrical arc through the electrolyte-saturated pad, the probe facilitates the instantaneous removal of discoloration while promoting the formation of the passive chromium oxide layer essential for corrosion resistance.

Maintenance and longevity are key aspects of the 48D803 design. The probe is built to endure the thermal cycles associated with high-amperage cleaning settings. It connects seamlessly to the SURFOX cable assembly, ensuring a secure, low-resistance connection that prevents overheating at the junction. For MRO professionals and fabrication shop managers, this probe represents the standard replacement part for maintaining the operational efficiency of SURFOX 104, 204, 205, and 305 units, ensuring that production downtime is minimized and weld quality remains consistent with ASTM A967 standards for passivation.
