Abstract
The present invention relates to a nozzle for a plasma arc cutting torch formed of a conductive material and having an exit orifice at one end for a plasma jet, comprising: a hollow body portion formed having a generally conical, thin-walled configuration sloping toward the exit orifice, and an enlarged head portion formed integrally with said body portion, said head potion (i) being solid except for a central passage aligned with said exit orifice, (ii) having a generally conical outer surface that also slopes toward said exit orifice, and (iii) having a diameter adjacent said body portion that exceeds the diameter of said body portion to define a cut back recess.
