I need to come back to this point.
How does this low pressure zone come? I always have the feeling when I'm sitting on my torch the fumes come back to my face. But I have to apologize, I have never heard of a low pressure zone. What is the theory behind it?
I really read a lot about how a ventilation set up should look like for beadmaking and in my class with Loren stump we discussed a lot about it. Everybody said my set up seems to be fine but I always complained about my feeling the fumes are coming back to me.
It would be a big help for me to know what I have to change.
Cheers
