Tig Cart, one or two 9” tanks?

[manac]

Designing a cart for my Dynasty. Any real need for two tanks?
Mig I’d do two but tig?

If you have to ask, then no. Just keep the spare argon tank in the next room out of the way.

Unless you're going to be doing a lot of thicker aluminum and want to keep a helium argon mix on hand, or an argon hydrogen mix for stainless

I have one on my tig cart and I wish I had put two. But I’d carry both argons there so when I run out in the middle of a job I can swap it very easily. I do have helium to mix in there when I need it, but I so infrequently use it that stays chained to the wall.

I used a long hose with quick connections and left my bottles chained to the wall. Was just easier for me

I've never had two tanks on a cart, even the fab shops I used to work in only had singles.

[MAC702]

If it's on a cart, it's because you want to move it around. Don't put another tank on it.

For me it would be a matter of convenient storage space. I rarely have to move my welder.
