INSTALLING A GAS CYLINDER
WARNING: Using an oversized gas cylinder can cause tipping, result-
ing in cylinder and equipment damage and personal injury. NEVER exceed
maximum cylinder weight of 100 lb.
CAUTION! Do not use an Argon/Mixed pressure regulator/flow meter with CO
2
shielding gas. To use CO
2
shielding gas, you must install a CO
2
gas pressure
regulator/flow meter (neither one included).

TO INSTALL A GAS CYLINDER
1. CAUTION! Do not use an Argon/Mixed pressure regulator/flow meter with CO
2
shielding gas. To use CO
2
shielding gas, you must install a CO
2
gas pressure regula-
tor/flow meter (neither one included).
2. USING AN OVERSIZED GAS CYLINDER CAN CAUSE TIPPING resulting in cylin-
der and equipment damage and personal injury. Do not exceed maximum cylinder
weight of 100 lbs. (45 kg).
3. With assistance, set the cylinder upright against a solid post or other stationary object
and use a chain or a heavy duty strap (neither included) to secure the cylinder in place.
(See Figure G)
4. Remove the protective cap from the cylinder. Stand to the side of the cylinder valve, and
open the valve slightly to blow dust and dirt from the valve. Then, close the valve. (See
Figure G)
5. Make sure the Flow Adjust on the Pressure Regulator/Flow Meter is turned off. Then,
screw the Pressure Regulator/Flow Meter firmly onto the cylinder valve. (See Figure G)
6. Attach the Gas Hose from the Pressure Regulator/Flow Meter to the Gas Inlet Valve lo-
cated on the Rear Panel of the Welder. (See Figure G)
7. Adjust the flow rate of the gas by turning the Flow Adjust. The typical flow rate is 20 cfh
(cubic feet per hour). Make sure to check the Welding Wire manufacturer’s recom-
mended flow rate. (See Figure G)

With help, set cylinder (not included) upright against post or other stationary ob-
ject. Use chain or heavy-duty strap (neither included) to secure cylinder in place.
