Several people in the US have mentioned Airgas as a source for nitrogen. Can you buy everything you need (tank, regulator, hose, etc.) from that type of store or do they just fill tanks that customers bring in?
Thanks!
Airgas won't sell regulators, you'll need to buy those online. If you are in a situation where you can't order items to your house, there are stores where you could have shipped to the store for pickup. Grainger for example.
As for the hose, you won't find that at Airgas either. You need a 1/4 inch medical hose, you may need to order that online from Amazon or whatever. A pharmacy like CVS or Walgreens may have some in store
I need an excuse for picking up a nitrogen cylinder.
So far I told them that I have a boyfriend that uses it for his business, but what business? I'm picking up an 80 cuft cylinder (size 16) so it's quite a bit of nitrogen.
What can I say he does?
I can't speak for all experiences ofc, but when I purchased my N2 from Airgas they didn't ask me any questions. I was in and out in 2 minutes. If you have to say something you could say laser cutting. The welding shop employee isn't likely to know much about that to question you. Just spend a few minutes online/chatgpt learning the basics.
Also I wouldn't say that it's for a business, just say hobby projects. Businesses would typically use like 300 cu ft tanks, and it might seem odd to the employee that your boyfriend doesn't just have a supplier already set up.
