ABSTRACT:
A stamping device (28) having a stationary base assembly (76), a carriage assembly (52) mounted on the base assembly for stepwise horizontal movement in a first direction relative to the base assembly, and a marker assembly (34) mounted on the carriage assembly for stepwise horizontal movement in a second, perpendicular direction. The marker assembly includes a marking pin (30) vertically actuable by an air cylinder (42) for impacting the tube sheet (14) adjacent a preselected tube (16). A control system (124) sequentially activates stepping motors (60,66) and the air cylinder to produce a dot matrix character (114) on the tube sheet.
