Abstract
Arc heater apparatus using total alternating current characterized by a pair of axially spaced cylindrical electrodes forming a narrow gap therebetween and connected to a first alternating current power source to produce an arc in the gap, each electrode having magnetic coil means for producing a rotating magnetic field at the arcing surface of the electrodes to rotate the arc, and the magnetic coil means being connected to a second alternating current power source which has an arc current zero aligned with that of the first alternating current power source.
