There is an alarm for the Argon bottle, I checked the pressure at the
bottle, it looks ok, but we do have an alarm in the shed. At this point,
I decide not to change it, since the other bottle is almost full. One of
the Argon/ethan bottle are going to run out, I will change it tomorrow,
since there is still one full argon/ethan bottle.
