Arc air gouging with carbon electrodes and compressed air is the fastest and cheapest process for cutting/gouging material in conjunction with repairs and the like. A carbon electrode is used to melt the material and, at the same time, a powerful jet of air blows away the molten material. The compressed air also cools the carbon electrode. Carbon electrodes can be used for the arc air gouging of unalloyed and low-alloy steel, stainless steel, cast iron and other metals.
A complete set of arc air gouging equipment consists of an arc air gouger, the Flair 600 or Flair 1600, alternatively the K4000 with mono cable.
