  • Patent number: 6005215
    Abstract: An electric arc spray gun wherein the spray tips can be precisely aligned is disclosed. The gun body includes converging wire guides located at an acute angle with respect to the horizontal. The diameter of the central portion of each wire guide is slightly less than the bore in which it is received permitting the wire guide to be deflected by the application of pressure to its outer surface. Such pressure is applied by the advancement or retraction of threaded fasteners received through the gun body. By deflecting the wire guides relative to one another, the spray tips can be precisely aligned. The wires which pass through the wire guides and the spray tips come together within the air cap on the gun resulting in the gun producing a very highly defined metallic spray.
