Carbon arc cutting arc gouging 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 blast of air.This is a method for cutting or removing metal by melting it with an electric arc and then blowing away the molten metal with a high velocity jet of compressed air.Robotic Revelations - American Institute of Steelstructural steel industry,and showed its first plasma robot,the CR4816,at the 2005 Steel Conference in Montreal.The plasma robot has become a key piece of equip-ment for all of our steel fabricating customers,either as a standalone machine or an Robotic Revelations BY GEOFF WEISENBERGER Geoff Weisenberger ([email protected]) is the
