An extensive amount of experimental material on investigation 
of the dependence of the erosion of a copper cathode on the main operating 
parameters - the current, the electrode temperature, and the magnetic 
field - has been generalized with the use of the thermal macroscopic 
erosion model proposed earlier. It has been shown that the basic regularities 
of the erosion, modeled in such a manner, are confirmed experimentally 
with a satisfactory correlation.
