Beschreibung
Zusammenfassung:	Provided is a fluid-cooled melting tool that can be used in methods and systems for manufacturing objects by additive manufacturing techniques, especially titanium and titanium alloy objects. In some configurations, the melting tool is configured to be a plasma transferred arc (PTA) torch and the deposition rate can be increased by increasing the flow rate of electric charge through the electrode made possible by the dual circuit cooling design of the torch. The fluid-cooled melting tools provided herein exhibit stable and repeatable PTA characteristics over wide range of current including current of 400 amps or more, whether pulsed or non-pulsed, and plasma gas flow inputs.
