This report described the general characteristics of a newly designed plasma electrode type plasma jet generator. This generator consisted of a nozzle constrictor, a rod anode and cathode which were put in each electrode arc chamber installed perpendicularly in the nozzle constrictor. A constrictor ring was set up at outlet of each electrode arc chamber. So the electrode spots were separated from the nozzle constrictor section and a U-shaped arc was ignited. The stability of the U-shaped arc was influenced by the constriction conditions of the cathode side arc column and the U-shaped arc was operated stably by selecting the experimental conditions, i. e. the improvement of the nozzle structure and the working gas flow form. The arc voltage-current characteristics was a rising characteristics and the arc input power was increased effectively. The jet power was up to 9kW at the arc current 110A and the thermal efficiency of the generator was much the same as the conventional type.
