An apparatus for marking metal in which a main carriage having a spray gun assembly with a stencil assembly mounted on it is moved toward and away from a piece of metal to be marked. Either the spray gun assembly or the stencil assembly is movable relative to the other in a direction transverse to the direction of movement of the main carriage. The stencil assembly has a plurality of stencil rings each having a plurality of cutouts with each ring being indexable so as to bring a specific cutout next to the piece of metal to be marked. After the indexing operation, the spray gun assembly is activated to spray molten metal through a cut-out in each stencil ring for forming the indicia. |
