Abstract
Producting process for converging high temperature plasma jets employs controlled high energy A.C. arcs between the anodes and the cathodes. Specifically, the device for the above process comprises 2 or 3 plasma jet devices so arranged that the jets meet in one point. Each device consists of an electrode and two pipes, one behind the other in line with the axis of the electrode.
