ABSTRACT:
Molten metal, slag and fumes created during the operation of a plasma-arc torch are discharged downwardly into a duct whose lower end is immersed in a tank of water. A stream of water is directed down the entire inner periphery of the duct and serves to cool and wash the duct. Fumes passing downwardly within the duct are directed into the tank and are quenched and cooled before bubbling upwardly into and being sucked from a housing which surrounds the lower end portion of the duct.
