K tank question...

[beegs]

Yo. So a long time ago I bought a torch and two k tanks from a nice fella named Butch in San Diego, the problem with the tanks is on the collar, they say 'PROPERTY OF SAN DIEGO WELDING SUPPLY'

Airgas told me they wouldn't replace/fill them, but an independent company down the street helped me out.
They sold me an owner tank (for way too much goddamned money, and was later stolen [beside the point]) and told me that everytime their tank rack filled up they would fill my tanks.
I am wondering if you all know a good way to help me out with these things, I went to this company so frequently to change out my owner tank, and randomly get handed one, or both my SD tanks because the rack filled up.
Please help me. Should I scrap these tanks? It is not worth the hassle.

Just keep trying different places. Some are chill some are not. I bought a really old k tank with a wierd looking valve, part of the knob broken off and the guy at Praxair swapped it out. I just had to pay hydrostatic testing fee like 30 bucks. Seems like that shop your dealing with is sketchy.

Electricity is too expensive here for me to think about making oxygen, if it was under or around 10 cents a kw hr I would be looking into that. I just try to conserve and I get a good deal on the tanks.

How/ where do I fill them on my own?

Read that

Also ask yourself how much oxygen you use. How frequently you torch. How handy you are at turning a wrench.

If you use more than a half a k-tank per day, and torch everyday, then the homefill might not work for you. If you only torch every other day or a couple days a week then this should work perfect. Make sure you are prepared to work on it when needed. They are very easy to work on and don't require any special tools, but they will need maintenance, its just a question of when not if.

There are other options for producing oxygen at home too. Using an oilless compressor, oxygen concentrators, and a holding tank, you can compress the oxygen to a lower pressure at a larger volume. This is much faster and more of an on demand oxygen system.

Saltcityglass,

They all sell oxygen equipment.

You can also build your own.

Since you have swapped your original tank out try Airgas and see if they will swap the different tank.
