Characteristics of Consumptions of Iron Anode and Cathode of Arc in Nitrogen and Chlorine

Abstract

In order to make the behaviors of the consumption-rates of anode and cathode clear, experiments have been performed chiefly in nitrogen and chlorine arc in the range of amperage 8 to 180A.
The results are summarized as follows ;
1. Below 40 and 15A, as the current decreases, the consumption-rates of anode and cathode increase respectively.
2. The consumption-rate of anode is hardly influenced by the surrounding gases, and the diameters of electrodes used, but it is almost constant above 50A.
3. The consumption-rate of cathode of the smaller diameter is higher than that of the larger diameter, depends upon the gases surrounding arc, and it is maximum in chlorine and higher in nitrogen than in argon.
