It is our aim to investigate the behaviors of consumptions of cathodes and anodes of arc, which are influenced by oxygen surrounding them. Iron, copper, aluminum and nickel bars of various diameters were used as a cathode or an anode in experiments. These consumption-rates in argon have been measured under the conditions that arc current is 90-180 A and argon flow 7-15 1/min. Summarizing the results as follows ; 1. The characteristic curves of consumptions of cathodes are particular to used materials. 2. Its orientation along oxygen including-rate translates to the direction of more oxygen including-rate, if arc current is made larger, smaller electrode is used, and electrode is better cleaned. 3. The consumption characteristics of anode are hardly influenced by oxygen including-rate, having particular values to used metals, but slightly in nickel.
