Abstract	In order to clarify the formative mechanism of penetration geometry at the anode in an arc melting process using gas tungsten arc plasma, a numerical model is useful to understand quantitative values for the balances of mass, energy and force in the melting phenomena. In the present paper, the whole region of an arc melting process, namely, tungsten cathode, arc plasma and anode is treated in a unified numerical model to take into account the close interaction between the arc plasma and the liquid anode. Calculations are made for the time dependent development of the penetration at the anode for the arc plasma in different gaseous atmosphere at a current of 150 A. The anode penetration geometry as a function of time is predicted in the arc melting process in argon and also helium.
