Title Experience with the introduction of torches for semiautomatic welding with fume aspiration in assembly plants
Original title Opyt vnedrenija gorelok dlja poluavtomatičeskoj svarki s otsosom aėrozolja na zavodah metallokonstrukcij [in Russian]
Bibliographic information Mar. 1985, No.3, p.43-44. Illus.
Abstract Description of a new electric welding torch. It has a lighter supply cable than previous models, which permits the torch and its air and electric lines to be made long enough to enable continuous welding of large vats, trusses and columns. Compressed air is supplied to cool the handle. A compressed-air ejector provides suction for an aspirator channel in the torch. Exhaust air passes through a specially designed filter where welding fume is collected. Depending on conditions in the factories where the new torch has been introduced, efficiencies of fume collection range from 70 to 100%, and fume levels in the welders' breathing zones have been reduced 15-20-fold. Substantial amounts of money have been saved by the elimination of the construction costs and heat losses associated with local ventilation systems.
