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. Further noise reduction can be achieved through selection of electrode composition, sound attenuating material juxtaposed to the operator's ears, control of arc voltage level and electrode stick-out. Velocity control can be achieved by modifications to existing air-carbon arc cutting and gouging torches.
