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.

1.CAUTION! Do not use an Argon/Mixed pressure regulator/flow meter with CO2 shielding gas. To use CO2 shielding gas, you must install a CO2 gas pressure regulator/flow meter (neither one included).

1. Cap.

2. Cylinder Valve.

Remove Cap, stand to side of valve slightly. Gas flow blows dust and dirt from valve. Close valve.

3. Cylinder.

4. Regulator/ Flowmeter Install so face is vertical.

5. Regulator/Flowmeter Gas.

6. Hose Connection.

Connect customer supplied gas hose between regulator/flowmeter hose con- nection, and fitting of welder.

7. Flow Adjust.

8. Solid post or other stationary object.

9. Chain or strap.

FIGURE G

2.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. (See Figure G.)

3.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.)

4.Make sure the Flow Adjust on the Pressure Regulator/Flow Meter is turned off. Then, screw the Pressure Regulator/Flow Meter (not included) firmly onto the cylinder valve. (See Figure G.)

5.Attach the Gas Hose for the Pressure Regulator/Flow Meter to the Gas Inlet Valve located on the Rear Panel of the Welder. (See Figure G.)

6.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 recommended flow rate.
