ABSTRACT:
A method and apparatus for arc spraying a pair of wires is disclosed. The invention includes feeding the wires to an arc at a controllable rate, where the rate is controlled in response to the current magnitude, or some other parameter of the arc. The arc is also monitored and the condition of the arc--whether there is a wire shortage or arc outage--is indicated to the user.
