摘要

Method and apparatus for collecting fume and/or slag generated by the operation of an air-carbon arc cutting and gouging torch. The apparatus includes a hood (20) which can hold torch (12) and is provided with a nozzle (24) to convey fume and/or slag from the hood (20). Air and water is introduced into the nozzle to cool the fume and/or slag and inhibit the slag adhereing to the nozzle. The slag and water are subsequently separated from the fume which is filtered and returned to the air.
