REDUCES THIS EXCESS GAS AND WASTE
GSS uses a smaller inside diameter
hose to reduce the volume of stored gas when welding stops. In addition,
a surge flow orifice built into the feeder end hose fitting limits the
peak surge flow at the weld start so it does not pull air into the shielding
gas stream. This orifice and the smaller ID hose create a small
pressure drop that also reduces the excess gas volume and waste.
stops, the GSS stores 80 to 85%
less gas than a conventional gas delivery hose.
Therefore there is 80 to 85% less gas to waste at the weld start. The
built-in flow rate limiter avoids having a turbulent starting gas shield-it's
The patented GSS has no moving parts and no knobs to adjust. Any reasonable, non-turbulent steady state gas flow rate can be set. (Note if welders are setting very high gas flow rates (we have measured flow at the gun nozzle of 150 CFH with the flow control knob opened wide) the GSS will limit these excess flow rate settings.) There is still
a controlled amount of extra gas at the weld start to quickly purge the weld
start area. System pressure remains above 25 psi to retain
Automatic Flow Compensation.
