The authers have previously described arc phenomena of underwater cutting using a consumable electrode water jet technique in fresh water at a depth of 0.3m. In this experimenta MG type electric source with a constant voltage characteristic was used, and observing arc phenomena whilst cutting proceed, possibility was seen applying a electric source with an AC constant voltage characteristic. Thus with this electric source, cutting efficiency, polarity effect, arc moving and selection of cutting conditions were studies, and also as a result of cutting of mild steel and aluminum in fresh water at a depth of 60m, the pressure of jetting water was not critical being 11kg/(cm)^2 and 8kg/(cm)^2 at 60m deep to mild steel and aluminum respectivity and fast cutting speed with high quality was obtained, even though heightened secondary voltage was applied with increasing of a water depth.
