Arc chamber of direct-current (dc) argon plasma torch and area just above the nozzle outside of this dc plasma torch wereobserved by hi-speed camera. System of reflecting mirrors and transparent silica arc chamberwalls were used to obtain simultaneous records of both i) cathode area with electric arc inside the palsma torch and ii) nozzle exit with resulting plasma jet outside the plasma torch. Such experimental arrangement allowed us to track localized repeating patterns (organized structures) in the arc chamber and in the plasma flow. identification of various organized structures - for different experimental conditions - according to their origin and typical development is presented in this paper.
