support.
• Keep the cylinder away from all areas
where it may be damaged.
• Never lift the welder with cylinder attached.
• Never allow the welding electrode to touch cylinder.
• Keep the cylinder away from welding or other live
electrical circuits.
BUILDUP OF SHIELDING GAS may

it is not in use.
SEE AMERICAN NATIONAL STANDARD Z-49.1,
"SAFETY IN WELDING AND CUTTING" PUBLISHED
BY THE AMERICAN WELDING SOCIETY.
------------------------------------------------------------------------
Maximum inlet pressure is 100 psi. (6.9 bar.)
Install the shielding gas supply as follows:
1. Secure the cylinder to prevent it from falling.
2. Remove the cylinder cap. Inspect the cylinder
valves and regulator for damaged threads, dirt,
dust, oil or grease. Remove dust and dirt with a
clean cloth. DO NOT ATTACH THE REGULATOR
IF OIL, GREASE OR DAMAGE IS PRESENT!
Inform your gas supplier of this condition. Oil or
grease in the presence of high pressure oxygen is
explosive.
3. Stand to one side away from the outlet and open
the cylinder valve for an instant. This blows away
any dust or dirt which may have accumulated in the
valve outlet.
4. Attach the flow regulator to the cylinder valve and
tighten the union nut(s) securely with a wrench.
Note: if connecting to 100% CO
regulator adapter between regulator and cylinder
valve. If adapter is equipped with a plastic washer,
be sure it is seated for connection to the CO
der.
5. Attach one end of the inlet hose to the outlet fitting
of the flow regulator. Attach the other end to the
welding system shielding gas inlet. Tighten the
union nuts with a wrench.

6. Before opening the cylinder valve, turn the regulator
adjusting knob counterclockwise until the adjusting
spring pressure is released.
7. Standing to one side, open the cylinder valve slowly
a fraction of a turn. When the cylinder pressure
gage stops moving, open the valve fully.
8. The flow regulator is adjustable. Adjust it to the flow
rate recommended for the procedure and process
being used before making a weld.
