Transformation of the glow discharge into the arc discharge is represented as the formation in the discharge of the current channel of higher electrical conductivity and apearance in the interelectrode gap of two electric circuits connected Inparallel and differing In their resistances. It is shown that the resistance of the glow discharge is determine by the ratio of the cross-sectional areas of the discharge and the disturbed zone. On this basis, the use of the heating schematics with anodesectionalization is suggested, as on If the measures to Increase the stability of glow discharge :t is determined, that the increase of the number of section improves the discharge stability, which provides the increase of welding efficiency.
