       The approaches that improve the efficiency of electric arc plasmatrons for materials processing: spraying, welding, cutting, gouging, etc. It is shown that an increase in the service life of the electrode system of plasmatron and thermal efficiency is achieved by profiling the discharge channel, stabilizing the cathode area and location of the cathode arc spot, the organization of the plasmatron with a split arc, creating the conditions for the formation of a diffuse attachment of the arc.
