This paper reports experimental observations of structure and behavior of arc-anode attachment and corresponding type of anode erosion. The plasma generated from argon-steam mixture in the torch WSPH 2000 was studied. A copper anode was situated outside the arc chamber in air atmosphere allowing direct observations by optical diagnostics. Conditions in the anode region and its basic configuration were changed. It led to different regimes of anode attachment from constricted and rapidly moving attachment to almost stationary and relatively wide channel. Distribution of copper vapors from the anode and a pattern of anode erosion were also significantly different for the both cases.
