Abstract: A metal spraying device of the kind in which two wires are fed along convergent guide ducts, and an electric potential is established between the wires, so that an electric arc is produced between the terminal ends of the wires. A jet of air is blown across the arc, removing metal from the ends of the wires in the form of minute droplets, the jet of air being directed against a workpiece to be sprayed with a metallic coating. The metal spraying device comprises a head made of insulating material (e.g. ceramics material), the head being provided with passages forming the guide ducts for the wires and for the jet of air. In this manner, the wires may be guided more accurately to the arcing zone, and turbulence in the jet of air may be minimized, producing an overall improvement in the quality of the spray which may be achieved.
