I'm still cutting and welding occassionally with a bottle I filled close to8 years ago. (big bottle) It is almost empty though finally.
I bought some old bottles. The O2 was hydroed in 96. It has gas in it. I feel I can use that up, and it will be okay. What about the acetylene? Is it still good after 5 years +?
I suspect you will get an unpleasant surprise when you find out how much the refill costs.
Good luck, YMMV
Yeah.... I've checked prices. If I did a lot of production I'ld probably get a plasma cutter. As it is I cut more steel with a saw than a torch. Since I finally got a little bit of a handle on my baby MIG I almost never braze or weld with my torch anymore. Still... I'll probably refill it. There are some really thin metal patching projects that are easiest for me with a torch.
I have some small "B" cylinders that were over ten years old when I finally sparked 'em up again. Worked just fine.
