Oxygen Concentrator??
 
Well my brazing kit is underway! My nephew gave me a used InvaCare unit on Christmas. But I now need to determine if it is real producing O2.
Thoughts?

wow, I should be nicer to my nephews. It probably has an alarm if it's not producing oxygen. Otherwise, put a candle in the output.

So would a candle burn more intensely? Hey, I am coming from a woodworking background!! Fire us foreign!

Hook up a torch with some kind of fuel and try to burn something!

Tandem Tom 12-27-19 10:14 AM

No torch yet! Just starting to acquire my kit.

A nearly pure O stream will really increase a flame's intensity. Never tried a candle flame to test this out although I have played with burning steel wool a long time ago. Don't do this with a wooden floor... Andy

Yeah, that's the idea. I'd light a wood splint on fire, blow out the flame, and then hold it in the oxygen stream. If there's more oxygen, it should burst back into flame.

Setup a candle yesterday and turned on the concentrator. The flame got bigger and brighter!! Seems like it works.
Now the hunt is on for a torch!

How many liters per minute is a good number , in searching for an Oxygen Concentrator on Craigslist?

The one I got goes up to 5 lpm
