The purpose of shielding the weld area is to prevent air from contacting the weld puddle and the electrode. A vacuum would be ideal. My idea is to get a very large amount of vacuum, pressurize it, and fill a cylinder with the pressurized vacuum and release it the same way you would use argon. If a user uses a large amount, they could condense the vacuum into liquid vacuum for efficiency. Dixon

Great idea! I frequently freeze boiling water. I often have a use for hot water, like making a cup of coffee.

I can't tell if you have no understanding of vacuums or physics, or if this is just a troll. "Liquid vacuum" ?
Vacuum welding is a commercial process, generally with lasers or electron beam. I remember having one guy tell me about a TIG process using vacuum, robotic welding in a vacuum chamber.

Will I need new flow gauges or will my current ones work ok?

We are still a month and several days away from April 1!

They'll work fine, just remember to connect them backwards ;-) Martin
This is, in essence, what is done now using air-gone.
If I recall correctly, pressurizing a vacuum changes Einsten's law from E=mC² to E=M²c

Has anyone tried using CO² with a tig ??---my guess is that it would dissociate in the intense heat.--Shore wood be cheaper tho...
Is this why I can weld better during stormy weather?

Pressurize a vacuum? Any fool knows that you can't do that. At any temperature higher than -21.7° Absolute, pressurizing a vacuum results in creating an anti-vacuum, and we all know what that leads to.
I suspect you've been huffing something, but I don't think it's vacuum, pressurized, liquefied, or cylinderized.
I've got a bottle of Liquid Vacuum to sell. You cant open it though or the air will rush in and then it will just suck =)
I faced a similar problem one time, out in the garden. There were some ripe cherries at the top of the tree. Couldn't reach them with my ladder, so I bent over, picked myself up by the ankles and raised myself to the cherries. Held on with one hand, and picked the cherries with the other.

I bought a can of that stuff just the other day. Got a can of Whoop Ass while I was there.

did you bother to bend over and kiss your...

Right..reverse the check valves. Got it!

I have.
You can watch the electrode evaporating.
