Abstract

This paper reports the results of some investigations into variations in the arc current, electrode shapes and arc gaps on the electrode, and excitation conditions in the arc system. The results obtained enable an analyst to predict the effects of varying these parameters on the conditions in the arc system. Arising from these investigations a new electrode has been designed which gives virtually constant anode temperatures throughout the lifetime of the burn.
