Abstract:
1. A method of performing a drag through electro-deposition process on a vehicle body, the method comprising the steps of: (a) moving the vehicle body through a drag through electro-deposition tank; (b) determining a current location of the vehicle body in the drag through electro-deposition tank; (c) determining a first non-zero electrical power to be applied to a first pair of anodes located in the drag through electro-deposition tank for the current location of the vehicle body in the drag though electro-deposition tank; (d) applying the determined first electrical power for the first pair of anodes via a first anode pair power supply; (e) determining a second non-zero electrical power to be applied to a second pair of anodes located in the drag through electro-deposition tank for the current location of the vehicle body in the drag though electro-deposition tank, the second electrical power being different from the first electrical power; (f) applying the determined second electrical power for the second pair of anodes via a second anode pair power supply; (g) determining an n (h) applying the determined n (e) repeating steps (b)-(h) until the drag through electro-deposition process is complete.
