Lorch EC-Cleaner 1000R weld seam cleaner

Clean and passivate weld seam: in just one step and 30 seconds

Chemical or mechanical cleaning processes adé!

Stainless steels get their corrosion resistance from a thin passive layer of chromium oxide. The heat during welding destroys this layer; the surface is now susceptible to corrosion. Tarnish and oxidation must therefore be removed after welding and the surface re-passivated. This is usually done either chemically or mechanically.

Chemical cleaning by pickling is toxic, requires long exposure times and leaves unsightly pickling marks. Mechanical processes by brushing or grinding are non-toxic - but almost always leave ferrites or iron oxides on the surface, which lead to new rust. Blasting processes, on the other hand, are associated with high investments. In addition, the surfaces must be passivated in a further work step - either by storage or with the aid of chemical passivation agents.

Choose the efficient way: electrochemical cleaning with light and carbon fiber brush

Passivate your weld seam thanks to the EC-Clean 1000 with light and a carbon fiber brush - easily and quickly! Through an electrochemical process, you can polish the workpiece mirror-smooth and even sign it tamper-proof. The EC-Clean is used wherever stainless steel is welded: from railing, container and pipeline construction to the furniture industry. The application is absolutely safe, as electrolytes are used which are also used in the food industry as an additive (phosphoric acid E338).

Pure efficiency

Millions of small arcs at the ends of the carbon fiber brushes remove all impurities on high-alloy stainless steels and even on non-ferrous metals such as copper in a flash. A second work step to passivate the weld seam is not necessary.

Pollutant-free

The EC-Clean 1000 cleans with the power of electric arcs completely without the use of toxic pickling chemicals such as hydrofluoric or sulfuric acid. Only non-toxic electrolytes are used, which are also used as food additive E338.

Cleaning and passivation in one step

Cleans thoroughly and quickly even in corners and edges Polishing the workpiece to a mirror-smooth surface Absolutely non-toxic electrolytes.
