Abstract

The appts. produces protective gas mixts and is fed independently with the two compnents, one being air. Each component is passed to a separate sealed chamber one chamber contg the air inlet nozzle and the venturi and the other the gas inlet. This second chamber communicates with the first through a series of holes.
