SURFOX Weld Cleaning System Welding of stainless steel produces a discoloration of the surface that must be removed to restore the corrosion resistance of the stainless steel and to improve its appearance. The patented Surfox Weld Cleaning System for stainless steel removes heat tint (bluing) and passivates through an electrochemical process. TIG and spot weld discoloration is removed instantly restoring the original mill finish. Neutralization is accomplished with Surfox-N to complete the cleaning process. This truly revolutionary system is: FAST Cleaning and passivation of a typical TIG weld is done at a speed of 3 feet per minute. SAFE Surfox-T electrolyte cleaning liquid is activated for aggressive cleaning through electrolytic action. EASY TO USE The cleaning liquid is delivered automatically to the cleaning tip by an integrated pump system – without spills, just the right amount and without stopping the cleaning action. How it works: 1) SURFOX-T electrolyte solution is delivered to the cleaning tip in measured pump strokes. 2) The special cleaning pad is soaked by the electrolyte. 3) Electric current activates the electrolyte and dissolves the discoloration of the stainless steel (electrochemical deoxidizing).
