To Install A Gas Cylinder

WARNING: Maximum cylinder height is 1 feet 7 inches (0.5m). Maximum cyl- inder weight is 22 lb., including gas. NEVER exceed either of these maximums.

1.CAUTION! Do not use an Argon/Mixed pressure regulator/flow meter with CO2 shielding gas. To use CO2 shielding gas, you must install a CO2 gas pressure regu- lator/flow meter (neither one included).

2.Thread the provided strap through the slots on the back of the welder. With assis- tance, set the cylinder onto the shelf at the back of the welder.

3.Secure the cylinder in place with the strap.

4.Remove the protective cap from the cylinder. Stand to the side of the cylinder valve, and open the valve slightly to blow dust and dirt from the valve. Then, close the valve.

5.Make sure the Flow Adjust on the Pressure Regulator/Flow Meter is turned off. Then, screw the Pressure Regulator/Flow Meter (not included) firmly onto the cyl- inder valve.

6.Attach the Gas Line (41) to the Pressure Regulator/Flow Meter from the Gas Inlet located on the Back Panel (6) of the Welder.

7.Adjust the flow rate of the gas by turning the Flow Adjust. The typical flow rate is 10-30 CFH (cubic feet per hour). Make sure to check the Welding Wire manu- facturer’s recommended flow rate.

WARNING

Risk of explosion!

While the Gas Cylinder is attached, this unit must only be transported using an appropriate welding cart (not included).

Transporting this welder any other way could result in the cylinder being damaged or ruptured, causing an explosion and, potentially, severe personal injury.
