Patent ID: 6983893

Claim:
An arc metalizing unit comprising: a wire retention unit housing one or more spools of wire whereby a rotational speed of said one or more spools of wire is controlled by a spool tension control device; a wire drive unit having at least two adjustable wire drives for pulling two wires from the one or more spools of wire and forcing the two wires to a spray gun; wherein said spray gun is in communication with an electrical energy source for oppositely charging each wire, said spray gun including wire guides for directing the oppositely charged wires to a common point within a spray gun body such that an electric arc between the charged wires is created thereby liquefying the wires; and wherein said spray gun is in further communication with a high pressure air source for propelling the liquified wire against a subject surface wherein the high pressure air is first passed through an air venturi tube within a body of the spray gun prior to the air propelling the liquified wire against the subject surface.
