First off, there is no argon hazard in your environment. Argon can only
harm by suffocation and that takes a LOT of argon, more than you have in
your tank. Put it in perspective. If you have the largest tank
commonly available, it contains about 282 cu ft. That's a box about 6.5
feet to the side. Relatively tiny. And argon is heavy so it will tend to

The only ventilation you need to worry about is for smoke removal if
you weld on something that makes smoke such as galvanized, and the
heat. TIG makes no fumes of its own unless you happen to burn a
tungsten. You don't want to get carried away with your ventilation
because it will blow away the argon and force you to use a higher flow.
That costs $$$.

It might be better from an access perspective but there's no significant
safety advantage other than removing any fire hazard from the house.
If your housekeeping is at all good, you really don't have much in the
way of fire to worry about.
In my current location, I do all sorts of welding in my basement. It is
a bit larger than yours and is air conditioned. The extent of my fume
control is to run the AC blower continuously so the electrostatic filter
can clean the smoke particulates out of the air when I'm stick welding
