Modeling and experimental studies of the electrodes erosion of plasma torch EDP-104A in nitrogen plasma were carried out. The resource of cathode and anode operation is determined by calculation. The conditions and performance of 178 cathodes were studied. The possibility of using natural gas to protect a tungsten cathode was investigated. The increase in the cathode life to the rated value was confirmed.
