Abstract
In a heat-plasma-jet, an arc is initially generated between opposed endless ends of a pair of electrodes and is moved along the opposed endless ends of the electrodes by generating magnetic fields having the same polarity at the opposed ends of the electrodes. Thereafter, a plasma generating gas is supplied into a region in which the arc is generated.
