Obtain gas cylinder and chain to
running gear, wall, or other
stationary support so cylinder
cannot fall and break off valve.
1 Cap
2 Cylinder Valve
Remove cap, stand to side of valve,
and open valve slightly. Gas flow
blows dust and dirt from valve.
Close valve.
3 Cylinder
4 Regulator/Flowmeter
Install Regulator/Flowmeter
face is vertical.

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.
7 Flow Adjust
Typical flow rate for CO shielding
2
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.

Supplied)
9 O-Ring (Customer Supplied)
Install adapter with O-ring between
regulator/flowmeter and CO
cylinder.
