<p>Embodiments of the present invention are directed to an air cooled, retract-start plasma cutting torch (200, 300) having improved performance. The torch (200, 300) com¬ prises any one, or a combination of an improved nozzle (213, 313), electrode (205, 305), shield cap and swirl ring (211, 311 ), where these components have improved geometries and physical properties which optimize plasma jet performance during cutting.</p> |
