Abstract
A plasma torch is formed from a hollow electrode forming a first gap to an isolated plasma tube, the isolated plasma tube forming a second gap with a plasma outlet tube having electrically common plasma tubes which terminate into a plasma outlet. The first gap and second gap of the isolated plasma tubes are fed by a source of plasma gas such that when a voltage is applied across the electrodes, plasmas initially form across the first plasma gap and second plasma gap. The formed plasmas spread laterally until the plasmas are formed entirely from electrode to electrode and self-sustaining. Plasma gasses which are fed to the plasma torch can be metered on both sides of the electrodes to steer the plasma arc attachment axially over the extent of the hollow electrodes, thereby reducing surface wear and increasing electrode life.
