Disadvantages are that the air jet causes the molten metal to be ejected over quite a large distance and, because of high currents (up to 2000A) and high air pressures (80 to 100 psi), it can be very noisy. Application. As air carbon arc gouging does not rely on oxidation .
The air pressure used and the design of the jets leads to velocities up to the speed of sound. The integral classifier recycles the coarse particles in the grinding zones thus limiting over-grinding by removing the fines. The grinding action is both by impact and by attrition.
