HOW THE
GSS
REDUCES THIS EXCESS GAS AND WASTE
The patented
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.
BOTTOM LINE
When welding
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
flow rate limiter avoids having a turbulent starting gas shield-it's
that simple.
The patented GSS has no moving parts,
no knobs to adjust, no limitations in setting steady state gas flow rate. 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.

Orifice.
A typical pipeline pressure is 50 psi. With cylinder
gas supply Regulator/Flowmeter ( left) pressures range from 25 to 80 psi depending
on gas type and model. Most
Regulator/ Flowgauges ( right) typically require 40
to 60 psi setting for 35 CFH flow rate.
