The article presents selected tapering functions useful when creating hybrid models and functions approximating static current-voltage characteristics of arc. The research work involved the formation and verification of families of static current-voltage characteristics with defined values of voltage ignition and the extension of approximating possibilities of the formulas through the use of tapering functions. The effective use of various functions approximating static characteristics in the
