4Regulator/Flowmeter Install so face is vertical.

5Regulator/Flowmeter Gas Hose Connection

6Welding Power Source Gas Hose Connection

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

7 Flow Adjust

Flow rate should be set when gas is flowing through welding power source and welding gun. Open pressure assembly so that wire will not feed. Press gun trigger to start gas flow.

Typical flow rate is 20 cfh (cubic feet per hour). Check wire manufacturer’s recommended flow rate.

After flow is set, close pressure assembly.
