Abstract Plasma of argon stabilized arc column, in a current range 3--11A, is investigated using emission spectrometric diagnostic techniques. Temperatures are evaluated using several methods: argon line to adjacent recombinational continuum intensity ratio, absolute emissivity of argon line, measurement of electron number density, and power interruption. Electron number density is evaluated from absolute emissivity of recombinational
continuum. The difference between electron Te and heavy particle Th temperature ranged from 4500K for 3A to 2300K for 11A arc current. By comparing the present with the previously obtained results, using the same arc device but with the introduction of water aerosol, it is concluded that water aerosol reduces the difference Te-Th and brings plasma closer to the partial thermodynamic equilibrium state.
