What equipment is needed for arc carbon gouging? Required equipment includes an air compressor, welding power source, carbon electrode and a gouging torch. The air carbon arc process is shown in figure 10-75. How much air do you need to arc gouge? A minimum extension of 2" should be used to prevent damage to the torch parts. Normal compressed air pressures for CAC-A range between 80 psi and 100 psi at the torch; higher pressures may be used, but they don't remove metal more efficiently. Use 60 psi (413.7 kPa) with the light-duty manual torch. Can you arc gouge without...
