SINOPSIS

The characterization of low current − high pressure tip-tip arc discharges in hydrogen − argon mixtures is presented. Main investigated parameters are: inter-electrode gap, mean arc current, H2/Ar mixture ratio and pressure. This was comprised between 0.1 MPa to 15 MPa. Mean arc voltage increases with pressure, H2/Ar mixture ratio and inter-electrode gap. The V − I curves shows typical non-thermal behavior of the discharge. The high pressure seems having only poor influence on the non-thermal regime arc transition.
