ABSTRACT:
The operating noise level of the air-carbon arc cutting and gouging process can be reduced by controlling the air velocity in the area where the air impinges on the arc column to between 90 and 170 feet per second. Velocity control can be achieved by modifications to existing air-carbon arc cutting and gouging torches.
