ABSTRACT:
A plasma jet generating apparatus including a torch center electrode, a torch nozzle, a first DC source, and a vortex flow/discharge unit. The unit includes a second DC power source, a gas diverter nozzle, and a vortex flow chamber. The second DC power source is used to create a high temperature and high power plasma jet. The vortex flow chamber, together with the gas diverter nozzle, is used to apply a thermal pinch effect to the plasma jet to be output from the gas diverter nozzle.
