An electro cleaning and electro polishing apparatus comprises with an inverter power source for the passivation, cleaning and polishing of metal surfaces by electrochemical action where the surface is contaminated from welding, other heat treatment or general fabrication and the contaminates .The invention improves the affect of the electrochemical action and accelerates the process. A device comprises pulse wave modulation enables the electrical frequency and wave form to be manipulated for selective removal of metal more easily and rapidly so that optimum polishing and corrosion resistance is accomplished. Furthermore to achieve this with the electrode that best suits the frequency and wave form ,the metal type, the finish of the parent, the finish of the fabricated piece, the amount of surface area, the shape of the surface and speed required. Further more a device for controlling the current is provided so unlimited electrodes and many permutations of voltage and current ratios are possible using the same inverter power source Drawings Fig. 1. Fig.2. Figure descriptions Fig.1. is perspective view of the inverter power supply apparatus. Fig.2. is a perspective view of an example of a hand piece operating a large carbon fibre brush style electrode. |
