ABSTRACT:
An inert gas is supplied in a conduit system at a pressure high enough to provide a desired shielding gas volume at each and all arc welding sites spread over a substantial work area and each welder is responsible for the performance of a lightweight, readily portable, security protected, fixed pressure output regulator of high accuracy preferably having a pressure gauge and two independent visible output flow meters and flow valves easily adjusted separately to provide proper shielding at the front and back of a weld simultaneously, but independently, under the personal control of each welder at each welding site with excellent mobility regardless of floor elevation, for an acceptable and individualized responsibility for each certified weld performed.
