Abstract: An apparatus and method for positioning each of the many silver electrodes into the tank of water such that arcing does not occur. This consists of a light or electromagnetic detector held in the tank of water so as to be close to the point where the silver electrode comes in contact with the water. When the silver electrode comes close enough to the water that an electrical arc occurs the detector observes this and sends a signal to the motor control. This signal is in turn sent to the motor causing it to turn. This turning action causes the treaded male rod to turn and it moves toward the water. As it moves downward it in turn lowers the silver electrode down until it comes close enough to the water that the arcing stops. When the arcing stops then the signal to the motor stops and the motor stops turning.
