Oxygen concentrator for torch?

Jewelry Discussion
1

I though someone said they have successfully used an Oxygen
concentrator with natural gas or propane with success. I just found
one in the trash, but my first effort did not work as the only
connector was with the humidifier. I plan to try again with a direct
connection. Am I wasting my time?

Thanks

maybe there’s a reason that thing was in the trash? They’re usually
costly enough people aren’t so quick to toss a working one, I’d
think…

I have a minor burner for glass beads, and have successfully used an
O2 concentrator with Propane for years. But it only puts out
6liters/minute and that may not be enough for acetylene.

Jacky, you don’t need a concentrator for acetylene, but you and get
another concentrator and hook the two together with you propane and
have a realhot torch, maybe to much for you minor burner? you better
check this out with someone who i using them this way. I use a unit
like you have on a big torch and get along ok for the things I make.
have fun

I believe I made that statement. Lampworkers (beads made by torch)
sometimes use oxygen concentrators, usually with propane.

I used such a setup, and it seemed to work fine. Apparently the
machines can suffer from lack of use; mine stopped putting out any
flow after I ignored it for about a year. There are replaceable
filters inside the machine. I suggest you talk to a medical supply
place that works with these machines to see what your options are.
Make sure they understand this will not be used for medical
purposes-should affect the cost, I should think.

I paid over $250 US for my concentrator over five years ago, so if
you get one cheap it should be worth a little experimentation.
