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
First: Please send me a quote for 330 cu.ft. of pressurized vacuum. Around 2500 psig would be adequate. Please use oxygen to pressurize the vacuum.
Second: Please quote 80 cu.ft vacuum with argon as pressurizer.
Thank you.
What kind of crazy request is this? Everyone knows the only way to (safely) pressurize vacuum is with more vacuum.
Gee, I'm sorry!
Forgot about the danger of a vacuum explosion if the vacuum gets contaminated. Especially the oxygen one: You don't want to expose an oily vacuum to high-pressure oxygen.
Darn!
My High School Physics teacher always drummed into our heads: "No extraneous atoms or molecules in a vacuum, Dammit! They'll wreck it!" I can't believe I didn't remember.
