A system and method of storing and reading parameter data associated with an electrostatic spray gun power supply is provided. The method includes, for example, the steps of reading parameter data associated with a power supply for a particular spray gun from a database and storing the parameter data in a memory device associated with the spray gun. The parameter data may include the drive current parameter information, for example, and additionally, spray gun type identification information. The memory device is preferably integral with the spray gun or a cable connector that connects to the spray gun. The data or information can be in the form of analog or digital information. After reading the spray gun power supply parameter data, the spray gun controller appropriately operates and monitors the spray gun to ensure that the spray gun power supply is performing properly.

Spray gun with data device and method of control

A first embodiment includes a control system which operates a spray gun to apply an even coating of flux to a circuit board or a plurality of different length circuit boards irrespective of the speed that the circuit board(s) move through a coating chamber. In a second embodiment, the control system pulses the spray gun on and off with a pulsing pattern that coats a plurality of zones of a circuit board with spray patterns of different length and thickness.
