Pickling and passivation
Clinox, the line of machines built by Nitty-Gritty for cleaning welds, represents the most complete and advanced range of machines for cleaning welds available in the world today. Taking advantage of the inverter technology that Nitty-Gritty first applied to its machines to clean welds, all Clinox are able to control the current, thus ensuring a wider range of voltage and amperage, which allows them to work in the best conditions and on any type of surface without running the risk of irreparably damaging the metal by touching it with a bare electrode, a recurring problem when using machines to clean welds equipped with a transformer. The difference is easily explained: the inverter, in the event of a short circuit, cuts the current in one thousandth of a second,
In a single step, guaranteeing maximum results without wasting time, all the machines for cleaning the welds of the Clinox line carry out both pickling, i.e. the removal of iron oxide (with its characteristic blue and brown-bronze color) - safeguarding so the aesthetics of the steel and avoiding its corrosion - than passivation, that is the restoration of the chromium oxide layer that protects the stainless steel from corrosion.
