The Walter Surface Technologies SURFOX 305 is a patented electrochemical MIG and TIG weld cleaning system that works to remove heat tint from the heat-affected zone of MIG, TIG and spot welds on stainless steel and aluminum. This system cleans the surface without disrupting passivation on stainless steel or altering the surface finish. The dynamic control helps protect the surface against micro-pitting. This system is designed to streamline weld cleaning and minimize downtime.
