This is used for:-

• Removing old plate

• Dissolving rust

• Electric etching

These tanks are set up in exactly the same way as a plating tank, except that they are wired up IN REVERSE. So you end up - DE-PLATING. Our

previous policy was to bolt the anodes/cathodes to the side of the tank, but now we prefer to cut a strip along the long side of the anode and use

this as the hanger. This enables the anode to be placed deeper into the solution, with no fear of contamination from the hanger.

ELECTRO-STRIPPING. The introduction of an electric current through the part dramatically increases the depletion of rust and old plate and assists in the cleaning/ preparation process.  The relevant solution (the pickles for this process are detailed in the Complete Plating Manual, is introduced into a de-plating / cleaning tank and the part suspended on a wire from the tank bar. The tank plates (cathodes) are wired to the negative side of your power unit and the tank bar to the positive. By varying the resistance, using bulbs or a rheostat, you can control the degree of de-plating / cleaning taking place.
