Abstract
In some aspects, nozzles for plasma torches can include a nozzle body having a proximal end and a distal end that define a nozzle body length and a longitudinal axis. The body can include an exit orifice defined by the distal end; a plenum extending from the proximal end to a plenum floor, a distance from the plenum floor to the distal end defining a plenum floor thickness, and a distance from the plenum floor to the proximal end defining a proximal end height; and a bore extending from the plenum floor to the exit orifice that has a bore length and a bore width. The nozzle body has a nozzle width in a direction transverse to the longitudinal axis. The nozzle body length is greater than the width and a ratio of the proximal end height to the plenum floor thickness is less than 2.0.
