Abstract

A metal jet cutting system, which includes a jetting head (9), a heater (30) and a power source (54), is used for modifying a workpiece. The jetting head (9) includes a crucible (11) and an inlet (17c) for receiving a feed stock (87) of a conductive material. The heater (30) melts the conductive material in the crucible (11) to provide a conductive fluid (80), which exits the jetting head (9) via an outlet. The power source (54), which is in electrical communication (50,52) with the conductive fluid (80), increases the temperature of the conductive fluid (80). The conductive fluid (80) is applied to the workpiece (70) to modify the workpiece.
