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.
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% CO
2
cylinder, make
certain the plastic washer is seated in the fitting
that attaches to the CO
2
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 WELD-PAK 3200HD
Gas Solenoid Inlet Fitting (5/8-18 female threads
