When you close the gas flow at common pressure regulator during the
welding process interruption, the outlet pressure in the connecting hose
raises up much above the optimal level (acc. to ISO 2503 up to 30%). Then
the volume of the gas, higher than really needed, is blowing through the
system after the welding process starts again by switching on the arc on
the welding torch. GS40 minimises amount of such waste gas cumulated
in the connecting hose. The optimal, predefined gas flow is delivered to
the welding process during all its phases.
Adjustable variant with the handwheel (GS40A) is to be used with
regulators with flow-meter, fixed variant (GS40F) with regulators with litrescaled
pressure gauge.
