Plumbing your shop for gas

The only places I have ever seen hard plumbed welding gasses are large manufacturing facilities that have argon stored as refrigerated liquid in a central location.

If you are the only user and you aren't welding 8 hrs every day, I don;t see the benefits. Just opens you up for way more potential gas issues.

I still like the cart and the bottle with it, some of my carts I put two bottles one 25/75 and one 100% Argon.

I totally agree, unless it's a school, or multi welding station shop, I don't see much advantage, and lots of disadvantages. I do like to have a small bottle around for portability and large ones for economy.

I knew PEX would resist splitting from freezing, but the way the manufacturers talk, they make it sound like it's still possible. If it lasts where you are, I would say it's pretty much freeze proof. Since I'm not freeze proof, I'll probably never have a chance to test that out. Still 81° Christmas is kinda ODD. Unless your in Australia. :D

Yeah, I see your point. No, I don't plan on welding that heavily, and if I did it'd probably make sense to just roll out the large cylinder.

Thanks to all for the comments! This gives me something to chew on for a while. There are definitely some things I didn't think about.

Cheers,
Richard

Does it make sense to "refill" the small bottles from the large cylinder? I know you'd never get a true fill on the little bottle, since it's just equalizing the two tanks, but you'd only pay to fill the large bottle at the cheaper rate.

I plan to do just that, one of these days. I believe Kempy has a transfer booster pump so he can get full fills from that setup.
