Abstract
An apparatus for supplying a soluble metal compound to an electrolyte solution uses a powder wetting device in a loop from a working tank. The powder wetting machine supplies the powdered metal compound directly into the electrolyte solution which rapidly dissolves to replenish the electrolyte compound during the treating process. The apparatus is particularly suitable for replenishing the metal salts consumed during an electroplating process.
