Dykker i arbeid. Brenner i stål med oxy-arc cutting system.

Oxy-arc cutting is an oxygen cutting process in which the necessary cutting temperature is maintained by means of an arc between an electrode and the base metal.

It is an oxygen cutting process wherein the severing/cutting of metals is effected by means of the chemical reaction of oxygen with the base metal at elevated temperatures, the necessary temperature being maintained by means of an arc between a consumable tubular electrode and the base metal.

The tubular electrode is a covered electrode with a small-diameter hole down through the center through which oxygen is blown. This method of cutting is quite similar to oxy-acetylene cutting process, except that the heat is supplied by the electric arc.

The oxygen arc process is used for cutting steel and non ferrous metals underwater. The tip temperature ranges from 10,000 to 15,000 degrees Fahrenheit.
