Oxygen-arc cutting is an oxygen cutting process in which metal is severed by means of the chemical reaction of oxygen with the base metal at elevated temperatures. The heat of the arc brings the metal to its kindling temperature and then a high velocity jet of pure oxygen is directed through a tubular cutting electrode at the heated spot. The metal oxidises and is blown away. The tip of the electrode, which is exposed to both heat and oxidation, is consumed in the process and needs to be replaced by the diver at regular intervals.
