802 028 / Ref. 803 379-A

Obtain gas cylinder and chain to running gear, wall, or other stationary support so cylinder cannot fall and break off valve.

1Cap

2Cylinder Valve

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

3Cylinder

4Regulator/Flowmeter

Install regulator/flowmeter to cylinder valve. Be sure that gauge face is vertical for viewing and adjusting.

5Regulator/Flowmeter Gas Hose Connection

6Welding Power Source Gas Hose Connection

Connect gas hose between regulator/flowmeter gas hose connection, and fitting on rear of welding power source.

7 Flow Adjust

Turn flow adjust screw to increase or decrease gas flow. Flow rate should be set when gas is flowing through welding power source and welding gun. Turn Range switch to Purge or Fan Only position. Press gun trigger to start gas flow. Typical flow rate is 20 cfh (cubic feet per hour). Check wire manufacturer’s recommended flow rate.
