ABSTRACT:
A low temperature melting metal such as tin, is contained in a small pot, heated by the flame of a burner. The metal is drawn from the bottom of the pot through a spray nozzle by venturi action of an air jet which forcefully throws molten droplets of metal against the surface to be coated. Means associated with the pot are provided to preheat the air stream before it comes into contact with the molten metal. Advantageously, the pot is closed by a cover, and air under pressure is supplied to the top of the pot, so as to force the molten metal towards the spray nozzle.
