Recently, a magnetohydrodynamic modeling of a 3-phase plasma torch has been developed giving a fair correlation with experiment results. In this paper, parallels instead coplanar electrodes have been considered. Results show a different arc discharge behavior controlled by repulsive magnetic forces instead of hydrodynamic electrode jet forces. These forces give a particular arc discharge influenced by frequency, current and gas flow rate.
