All,

Newby question here -and I know the answer could vary by a great deal due to many factors but... I have a 150cuft argon tank that came filled showing 2100 PSI. I'm trying to gauge how much TIG welding (roughly) that gives you. Yes, I understand it depends on many, many things including flow rate and how efficiently I operate the torch etc... but, I'm looking for a ballpark estimate.

So, assuming I'm running about 15 CFH, making lots of mistakes while practicing on a mountain of AL drops, how many hours (roughly) do you think I should get out of the bottle?

Thanks for your patience on this question. I had problems with my initial setup and wasted a lot of time (and argon) in the first couple days. I'm down to 1800 PSI. ...Just trying to get a handle on how long I can expect a tank to last.

Thanks

Ray
