5-13. Connecting Shielding Gas Supply
Obtain gas cylinder and chain to
running gear, wall, or other
stationary support so cylinder
cannot fall and break off valve.

Cylinder Valve
Remove cap, stand to side of valve,
and open valve slightly. Gas flow
blows dust and dirt from valve.
Close valve.

And Mixed Gas (MIG) Hose
Connection or Argon (TIG) or
(Spool gun) hose connection.
Connect gas hose between
regulator/flowmeter gas hose
connection for gas type being used,
and the fitting on rear of welding
power source. Only one gas hose
can be attached at a time.

Flow Adjust
Typical flow rate for CO

shielding
gas and MIG (GMAW) welding is 15
to 30 CFH (cubic feet per hour)
(7.05 - 14.1 LPM)and mixed gas is
25 to 45 CFH (11.75 - 21.15LPM).
Typical flow rate for Argon shielding
gas and TIG (GTAW) welding is 15
to 25 CFH (7.05 - 11.75LPM) and
aluminum MIG (GMAW) welding is
35 to 45 CFH (16.45 - 21.15 LPM).
Check wire manufacturer’s
recommended flow rate.
