Abstract
PURPOSE:To have stable plasma jet with high output by interposing an effective swirler between an electrode member and an electrode nozzle, and supplying a non-oxidative working gas into the discharge space. CONSTITUTION:Pilot arc discharge is made between an electrode nozzle 10 and an electrode member 20, followed by main arc discharge to form a main arc column 100. N2 gas as a non-oxidative working gas jetted out of a swirl nozzle hole 31 of a swirler 30 becomes a strong swirling stream in the hole 31, and sinks in a recess 12 of the electrode nozzle 10 as shown by arrow Q. At this time, the N2 gas generates swirl in the vertically stretching discharge space 200 from the electrode member 20 to nozzle hole 11, and the main arc column 100 is held in restraint in the low pressure region of the swirl stably. This prolongs the discharge gap length, and the discharge space 200 is filled with non-oxidative N2 gas even though the discharge point becomes high temp. at the time of main arc discharge, that suppresses oxidation and combustion, and as a result the electrode nozzle 10 and electrode member 20 are prevented from fusion damage.
