My last 200lbs of Argon.... first bottle ever

admin

I spent it doing a completely pointless thing..... using pieces a made for a totally different project that never got used......I was too lazy to put the 3/32 Lanthanated in.... so I just used the 1/16" Red instead...... Worked well enough.... since the project had no point..... and I didn't even care about contamination... since I was done for the day anyway.....100lbs gone..... Good enough... time for bottle #2...... Attached ImagesPrecision TIG 185 and MP 210Bobcat 225NTCutmaster 42O/A tanks.... 2 Argon tanks...... 2 C25 TanksFacebook......

Reply:100 lbs, or 100 CF?
Reply:I wish I knew enough to answer smartly......The flowmeter I have is a good one...... and I put it at about 15 for most jobs.... the gauge started at 2000...... today was at 500..... then.... at the end of the day.... was just below 100....... I just figured it was lbs........ but Cubic Feet is probably the right term.....HellifIknow......Precision TIG 185 and MP 210Bobcat 225NTCutmaster 42O/A tanks.... 2 Argon tanks...... 2 C25 TanksFacebook......

Reply:I think your talking about psi
Reply:I know that feeling. Sometimes there's not really enough CF left in the tank to start work on something larger, but you start eyeballing it if you get bored and end up finding something to burn a the last few CF on. What you ended up with looks pretty cool. Maybe a piece to hang from the ceiling or from an awning outside on a deck if it isn't too heavy.For me the other night, it was cutting up some 20thou SS I had leftover from an electronics box and making a little 5 sided box out of it. Entirely pointless in terms of a project...but, learned a few things about trying to just fusion weld an exterior corner instead of using filler and ended up with...well..a thing. It's maybe all of 3x3x2.5" so pretty much only good for paperclips or screws haha.Also..how much of a pain getting a torch into REALLY small spaces can be and playing with stick out.

Reply:I gotcha on the terminology...  maybe I can try to clear things up a bit.Cubic feet is the actual amount of gas that's crammed in the cylinder.  It's basically how big of a balloon the gas would fill if you let it all out.  PSI (pounds per square inch) is the actual pressure inside the tank.  It measures how hard the gas is trying to escape. Since a gas will always expand to fit its container, PSI is used as the reference gauge as to how full a tank is. It directly correlates to the volume of  gas compressed into a given cylinder, however 2000 psi in a 100 cubic foot tank and 2000 psi in a 250 cubic foot tank would equate to different volumes of gas.  LBS (pounds) is a measure for liquefied gases like carbon dioxide and propane.  The pressure in one of these tanks can't be higher than the vapor pressure of the liquid inside (which is temperature dependent), so the amount of gas is measured in pounds, instead.  Certainly you've heard of a 20# propane tank, or a 50# co2 cylinder.
Reply:I've screwed up a project by not paying attention to the tank...  Airgas wont sell or rent me the bigger tank because I'm not a business. so I have to settle for the next size down, and it tends to go faster then I would like.. I was tigging up an aluminum tank one day and all the sudden, the tungsten was getting super hot, and I started getting contamination.. it took a good ten minutes for me to realize I was out of gas.. DOH!  Airgas was closed that day, and I had to start that project all over again.. I was pissed to say the least..  I bought a second tank, and I pay VERY close attention to how much gas I have left...www.thefusionsolution.com

Reply:Airgas out here in Colorado is just fine.  It must be a store to store thing.  I can rent any size bottle I can move in the truck...
Reply:WooooooHooooo, go Fexal Congrats, thats an accomplishment. If I were you, I'd hang onto that random object, it is cool, and you can look back at it later...But then again, Im a packrat, atleast with things Ive made. I still have the first thing I ever welded together, a few joints from school, first beads with the Stickmate, etc... lol...Anyway, thats an accomplishment [Account Abandoned 8/8/16 Please Do Not Attempt Contact Or Expect A Reply].

Reply:Originally Posted by bratkid63That is why I hate Airgas. They bought out one of the locally owned welding supply stores several years ago. Had the same issue with them, trying to upgrade from 120 CF bottle to a 250. Clerk behind the counter was a real A-hole. I swore I'd never set foot in that store again, and apparently many others felt the same way, as they only lasted about 2 years before folding up their tent and moving out. Good riddance.
