HOOKING UP GMA SHIELDING GAS

WARNING

CYLINDER may explode if damaged.

• Gas under pressure is explosive.

•· Always keep gas cylinders in an upright position and always keep them chained to the undercarriage or a stationary support.

See American National Standard Z-49.1, "Safety in Welding and Cutting," published by the American Welding Society.

The user must provide a cylinder of shielding gas, a pressure regulator, a flow control valve and a hose from the flow valve to the gas inlet fitting of the LN-9 GMA. See Figure A.11 and install as follows:

1.Connect the supply hose from the gas cylinder flow valve outlet to the 5/8-18 female inert gas fitting on the back panel of the LN-9 GMA wire drive section.

2.Install the barbed fitting and union nut to the 5/8-18 female inert gas fitting on the front of the LN-9 GMA. Connect the 3/16 inch (4.8 mm) I.D. gas hose from the gun to the barbed fitting.

When you need to remove the gun, you can easily detach this fitting by loosening the union nut.
