Claims9
A plasma torch whereby a plasma arc emanating from an electrode in a torch body is pinched through a torch nozzle in the torch body and is then flushed into a working zone, characterized in that said torch body is of a flattened cross section transverse to an axial center line thereof and said torch nozzle is eccentric with said torch body and has a nozzle axis that is deviated in position from the axial center line of said torch body substantially in parallel therewith in a direction in which said flattened transverse cross section is elongate.
A plasma torch whereby a plasma arc emanating from an electrode in a torch body is pinched in a torch nozzle and is then flushed therefrom against a workpiece, characterized in that said torch body has attached thereto a workpiece contacting cap, said cap being provided with a gas venting recess for permitting an exhaust gas to be swirled out therethrough in a direction which is the same as a direction that a plasma gas swirls.
