Torch is getting hottter
Hey all
I have a National 8 , and since the last 3 uses it got so hot that when I touched it, it left a mark on me. Could something?? be leaking. Anyone else has that problem? Any ideas or tip greatly appreciated. Thanks Katja |

I had noticed the same thing with my Minor. It turned out that a screw was getting worked loose and a part was slipping out of place. I discovered this when the torch fell apart when I was in the middle of a bead. Yes, I did almost have a freakin' heart attack. :shock:

The part that slipped on your torch, Chris, was probably the heat shield. It is a good idea to check and make sure that the heat shield is placed properly and the screw is tightened when you first get your torch. Sometimes, not often, things can loosen up during shipping. I think that the heat shield is supposed to be positioned so the tubes are exposed by at least 1/8". I am not positive about that number, maybe one of the Nortel distributors can chime in. You can also call Nortel. They are friendly and will be happy to answer questions. It's important that the heat shield not overhang the tubes.
Katja, have you checked the "O" ring of your torch? Sometimes those can fail and cause the torch to overeat. |

Thanks for the info. I use tanked 02 at 10 pressure.
Ok where are the O rings. Inside the torch? Guess i have to get my manual. Katja |
Yes, it's inside the torch along a shaft thing.
