Steel-Tubular Electrode Cutting Technique (cast iron and non-ferrous metals). Cast iron and non-ferrous metals do not oxidize; therefore, underwater cutting essentially becomes a melting process. There is no chemical reaction of the oxygen and the base metal. Therefore, the only benefit realized by the oxygen is the mechanical effect of blowing the molten metal away. Since the melting process takes

This technique is slightly different from that used on thick plate. Instead of maintaining the electrode tip in the cut and pressing against the lip of the advancing cut, the tip should barely touch the plate

The electrode is 14 inches long with a 5/16-inch outer diameter and a bore diameter of slightly less than 1/8 inch. The waterproof flux coating is similar in composition to the coating
