You never get pure oxygen, but it should be at least 93%. What is the smell, other than weird? Musty, moldy? If so, it might be mildewy inside and need some cleaning. Not sure I would try to clean the tubing though unless it looks easy to disconnect/reconnect.

If it is running your torch, it is generating oxygen, but it sounds like your purity is low.
