I am somewhat uncomfortable to have control nobs too hot to touch. I am reluctant to burn my fingers and also wonder about safety issues and how long the hoses will last before they crack or break.
I am thinking about getting a different torch. One that is quieter and does not have the heat issues the National 8 appears to have.
I should add that I have no experience with any other glass torches to date so these issues may just be standard for other glass torches as well. I may also be a bumbling fool that cannot figure out how to use the torch.

I've read that some older 8m's have something wrong with an O-ring that has something to do with the overheating issue. You might contact National to see if they have anything to say about it.
I've never had trouble with mine, but I've only ever ran it with premix tips.
