Abstract
Dependence of the arc gap voltage in pulses of current at straight (SP) and reverse polarity (RP) and also effective values of voltage on current and duration of current pulses at reverse polarity is considered. The decrease in voltage in pulses of current at straight polarity down to anomalously low values at increase in duration of current pulses at reverse polarity is outlined.
Keywords: volt-ampere characteristics, non-consumable electrode, argon arc welding, AC arc, square shape voltage
