Hi Ed, what personal precautions do you take when brazing aluminum?
What safety data is provided with the brazing rod?
I believe the fumes, mostly from the flux, are extremely harmful to your lungs ... lungs cannot be repaired.

That may work well, Dale. But, I have stacks or aluminum brazing rods that
I could never get them to do more than sizzle around like a drop of water in
a hot skillet {:>). The HTS-2000 was the first one I had any success with
and did not require special prep of the work area.
I realize that other folks must have had success with the other brands, but
I did not. I mean enough folks must have continued to buy the products to
keep them in business - but the HTS-2000 just flowed great and just a brief
scrub with a stainless steel brush was enough to get adherence.
I use it to braze my aluminum intake manifold (since I don't weld) and am
still flying with it and no problems thus far.

At a trade show, a couple of months ago, I picked up a bit of this:

Seems to work pretty well.
