  • Abstract
    The stability of free-burning copper arcs in air has been investigated using a variety of electrode configurations. The longest lifetimes are obtained using a hollow-cratered cathode which yields lifetimes of more than 10s in the current range 50¿250 A. These times are more than one order of magnitude higher than the lifetimes obtained with a pointed-rod cathode. Distortion of the electrode surface, due to prolonged arcing, reduces the arc lifetime.
