WELDarc Gouging Carbon DC

Gouging Carbons, Arc Cutting Carbons, Arc Air Carbon, previously known as air arc cutting is an arc cutting process where metal is cut and melted by the heat of a carbon arc. Molten metal is then removed by a blast of air. It employs a consumable carbon or graphite electrode to melt the material, which is then blown away by an air jet. Features and Benefits: This process is useful for cutting a variety of materials, but it is most often used for cutting, and gouging aluminium, copper, iron, magnesium, and carbon and stainless steels. Because the metal is blown away by the air jet, it does not need to be oxidised. This process differs from plasma cutting operations because in air carbon cutting, an open, or un-constricted, arc is used, and the arc operates separately from the air jet. Air pressures for the jet usually vary from 60 to 100 psi. The carbon electrode can be worn away by oxidation from heat build-up and can be reduced by coating the carbon electrodes in copper. The sharpened carbon electrode is drawn along the metal, an arc forms and melts the metal. The air jet is then used to blow away molten material. This can be dangerous as the molten material can be blown substantial distances. The process is also very noisy. Warning: Always wear appropriate safety gear/clothing and protect yourself, as well as others from molten metal and noise. Contact GWS for all the safety gear requirements you may need.
