38. An electrode for a high visibility plasma arc cutting torch comprising:
-
an elongated electrode body having a first end and a second end, the body defining a bore in the first end for receiving an insert, the electrode body including; (i) a first body portion extending from the first end; (ii) a second body portion extending to the second end; and (iii) a heat transfer zone located relative to the first body portion at the first end of the electrode body, wherein during operation of the plasma torch at a current greater than about 15 Amps, the heat transfer zone is in thermal communication with a cooling gas and is configured such that a majority of heat generated during the operation of the plasma torch is removed from the heat transfer zone. - View Dependent Claims (39, 40, 41)
