A simple method of pulsing constricted electric arcs to high power inputs is described. Using this method, peak power inputs six times greater than can be run continuously have been achieved. An analysis of this method has been made for argon to determine the maximum temperature to be expected as a function of arc channel diameter and generator construction material. In addition, a number of methods used for electric and spectroscopic diagnostic studies of the pulsed high current arc column are discussed.
