  • Arc thermal spray gun apparatus
    Patent number: 6663013
    Abstract: An arc spray gun has a pair of wire guides that guide two metal wires to an arc zone near the wire tips where an electric current through the wires effect an arc, thereby melting the wire tips. The wire guides are of a two-part design. One part is easily removable without the need for tools. Generally, each removable part of the wire guide is temporarily held within a stationary wire guide by an O-ring. A retainer then holds the removable wire guide firmly in place. A gas cap keeps the retainer firmly against the removable wire guides while the gun is in use.
