ABSTRACT:
A method for cutting or gouging a metal object submerged in a non-volatile liquid medium by establishing an arc between the consumable electrode and the workpiece to heat and melt the metal and simultaneously directing a stream of the liquid medium at the molten metal to impinge upon and carry the molten metal away from the arc and the workpiece. The inventive method replaces conventional oxy-arc underwater cutting methods.
