2.With the cylinder securely installed, remove the cylinder cap. Stand to one side away from the out- let and open the cylinder valve very slightly for an instant. This blows away any dust or dirt which may have accumulated in the valve outlet.

WARNING

BE SURE TO KEEP YOUR FACE AWAY FROM THE VALVE OUTLET WHEN “CRACKING” THE VALVE. Never stand directly in front of or behind the flow regulator when opening the cylinder valve. Always stand to one side.

3.Attach the flow regulator to the cylinder valve and tighten the union nut securely with a wrench.

NOTE: If connecting to 100% CO2 cylinder, make certain the plastic washer is seated in the fitting that attaches to the CO2 cylinder.

4.Refer to Figure A.6. Attach one end of inlet gas hose to the outlet fitting of the flow regulator and tighten the union nut securely with a wrench. Connect the other end to the Pro-MIG 140 Gas Solenoid Inlet Fitting (5/8-18 female threads — for CGA — 032 fitting). Make certain the gas hose is not kinked or twisted.
