Abstract
A plasma arc torch is provided that includes a tip having an improved life. The tip defines a first set of fluid passageways, a second set of fluid passageways and an internal cavity in fluid communication with the first and second fluid passageways. The internal cavity includes a base portion disposed proximate and surrounding a central orifice of the tip. A first set of fluid passageways allow for entry of a cooling fluid into the tip and a second set of fluid passageways allow for exit of the cooling fluid from the tip.
