The following nozzles are high performance nozzles to be operated with a pulsed atmospheric arc (PAA®) plasma generator (PG31) and a pulsed power supply (PS2000).   
The nozzles achieve the following functions: 
- focussing of the plasma flame 
 - acting as a grounded cathode to confine the high power electric arc
 - forming of the cavity to excite the process gas
