Oxygen & Acetylene setup advice

I also have a set of the 10 cu ft bottles in a plastic carrier like is shown above in some of the posts. I rarely use it because the bottles are so small they run out really quick. Particularly if you are cutting.

If you are buying off Craigslist or on line ask the seller to measure the bottles before you go. My first MiG bottle I bought I drove an hour to get. When I got there it was only a 10 cu ft bottle. Looked larger in the picture. But I drove so far I bought it anyway.

The second one I bought was a 300 cu ft. Looked smaller in the picture. I also drove a long way to get it, so I bought it. Barely fit in my car. I was so big that it would crush my harbor freight welding cart. I had to bolt it to the wall & run an air hose. So I have screwed up both ways.
