darock,

I just use a cheep plumbing propane torch. It is just hot enough. I think 600 degrees? It says on the package. Aluminum melts at 750 degrees or something like that. The propane torch is cool flame so easy to avoid melting the aluminum, but hard to lay a bead with, but no problem. Just get the material on the joint then "paint" it where ever you want with a piece of wire used as a brush like I mentioned previously.and you have to heat soak everything to get up to working temp. A much finer hotter flame might be better. but for fixing mufler pipes the propane works fine. Aluminum brazing is not as good a weld but much better than JB weld. So quick and simple.
