Vaccum Pump

Occasionally the Argon gas bottle gets contaminated. When that happens, it is necessary to evacuate the bottle with a vacuum pump before refilling. The Q200 requires 99,998% pure Argon. When it isn’t being used, you will have to evacuate the bottle before refilling. The Q200 doesn’t like air in the Argon. So if you let the bottle run empty and didn’t close the valve before removing, then you will need to evacuate the bottle.
