So the danger is that if the torch was run on to low of a flame for a extended period ( the larger the torch , the shorter to time) the metal the face is made of would begin to melt. This is why its important to size the torch to the work you plan to do. Running a large torch on low settings is just asking for problems.

THIS is the reason I like having this guy around when I'm at my torch. It's the reason why I'm still intact & why my torch hasn't suffered meltdown. If I have a problem...he rescues me. He chose my torch, set everything up and showed me how to use and care for it. It's also handy to have my resident fireman around while I'm playing with fire...one never knows...
