Description	Anode processes taking place during pilot arc and cutting phases of plasma arc cutting (PAC) are experimentally studied. The experiments are carried out on commercial equipment so as to bring the studied conditions close to real operating conditions in application areas. The obtained results show the significant role of anode attachment in both process phases. In the pilot arc phase long residence time of the anodic spot results in electrode wear. An increase in the flow rate of the plasma medium facilitates anodic spot movement. In the cutting phase, the anode attachment significantly affects the kerf shape and surface morphology. Lack of its movement deeper inside the kerf leads to different heat transfer conditions at the top and bottom of the material and results in different surface roughness values. Facilitating the anodic spot movement towards the plate bottom is desirable to improve the cut quality Anode processes taking place during pilot arc and cutting phases of plasma arc cutting (PAC) are experimentally studied.
