To simplify the heavy-duty weld cleaning procedures, use Walter 54B036 Surfox Mini Narrow Tungsten Insert, a highly conductive right angle insert. The welding tungsten insert is especially manufactured to be used with Surfox high conductivity pads (54-B 026 or 54-B 040) and clamp ring 54-B 002 or cleaning hood 54-B 005. The conductive tungsten insert allows for easy passivation required for effective cleaning of welds. It can be useful during the electrochemical TIG, Spot, and MIG weld cleaning and effectively removes the surface contaminants like heat tints from stainless steel materials.
