SHIELDING GAS CONNECTION

WARNING

CYLINDER may explode if damaged.

• Keep cylinder upright and chained to support.

Keep cylinder away from areas where it may be damaged.

Never lift welder with cylinder attached.

Never allow welding electrode to touch cylinder.

Keep cylinder away from welding or other live electrical circuits.

bUILD UP OF SHIELDING GAS MAY HARM HEALTH OR KILL.

• Shut off shielding gas supply when 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 out- let.

4.Attach the flow regulator to the cylinder valve and tighten the union nut(s) securely with a wrench. Note:

if connecting to 100% CO2 cylinder, insert regulator adapter between regulator and cylinder valve. If adapter is equipped with a plastic washer, be sure it is seated for connection to the CO2 cylinder.

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.
