Hi,

I started using Smith little torch with oxy concentrator and a disposable propane tank for jewelry making. I noticed that when I turn the oxy concentrator on there is a weird smell coming out from the oxygen line (the propane is shut off at this point so it's not it). If I breath that for some time I get a headache. If I turn on the propane and light the torch and mix the two I get orangy/redish flame around the inner blue cone instead of a light blue one when I mix in the "oxygen".

I tried googling but cannot find anything about what the smell might be. I assume the oxy concentrator is somehow malfunctioning and whatever is coming out of it is not a pure oxygen but I don't know how to test this or how to find out what is going on. Anybody has any ideas?

Thank you!
Tereza.
