Setting Up the Argon Regulator:
The argon regulator (pictured below) is included with your unit. Setting it up to your
argon bottle is easy. Simply screw in the valve to the bottle and set the pressure to
about. Use 100% Argon at 15-25 CFH (cubic feet per hour). Set the gas flow using the regulator
on the gas bottle. Use higher flow when extending the tungsten electrode to reach into corners or
gaps. We recommend about 18 CFH. Remember, that you also have a post flow setting on the
unit to pass more argon after the arc to cool the electrode.
