CARBON AIR ARC GOUGING

Air carbon arc cutting is an arc cutting process in which metals to be cut are melted by the heat of a carbon arc. The molten metal is removed by a high velocity blast of compressed air. The air jet is external to the consumable carbon-graphite electrode. It strikes the molten metal immediately behind the arc.

The air carbon arc cutting process (CAC) is used to cut metal, to gouge out defective metal, to remove old or inferior welds, for root gouging of full penetration welds, and to prepare grooves for welding.
