Arc air gouging, 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.
This process is useful for cutting a variety of materials, but it is most often used for cutting, and gouging aluminum, copper, iron, magnesium, and carbon and stainless steels. Because the metal is blown away by the air jet, it does not need to be oxidized. 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.
The R7000 has been specifically designed for MMA and Arc-Air gouging. The unit delivers an impressive 700-A output current at 70% duty cycle – making it suitable for any working environment.
