minor torch suddenly not working! Help!!
I have a Nortel Minor burner hooked up to an extreme oxygen EX-5 oxy concentrator and tanked propane. I've kept the EX-5 set at the max (5) and the propane regulator set to 5 psi. This set up has been working for 6 months.
About two weeks ago the flame started pulsing. Then suddenly, it wouldn't even accept the oxygen. The oxygen blows the flame away from the end of the torch, and then the flame goes out. I thought the regulator was bad, so I bought a new one.
But nothings changed. I've tried the propane psi higher and lower, but nothing works. I can manage getting a neutral flame for about two seconds before it pulses and then is blown away from the torch end.
It's like the oxygen is too strong. It blows the flame so that it is inches away from the end of the torch, then it goes out.
Please Help! If you don't know what is wrong, maybe you know who I can ask?
Thank you so much.
Nancy
