Nice welds. My dad used to gas weld everything. I wish I paid more attention to the stuff when he was still alive Unfortunately, I didn't get into it again until my mom asked me to clean out his workshop last year.

Wow nice welds, I too have brazed alot yrs ago. but now it seems, with a plasma cutter, TIG and MIG, I don't use the torch for much except heating things, same with stick, just sits there mostly. Like Dabar, I am interested in it so anything you've made I'd like to see. Also any info is appreciated.Scott

I have to warn you, that stuff isnt "welding" at all, its more like a low temp braze. The cored rods are also actually brazing rod. The drawback is that the brazing is not ductile at all, and is designed to be used with surface area I.E. a lap joint. Butt welds with brazing material arent that reliable and unfortunately the entrie area has to be removed to re-do a braze as the material infects the parent metal at welding temp.
I use either Allstates aluminum welding flux, or the flux sold by Kent at www.tinmantech.com. He also is a good source of learning material. Use a good spring water like evian with the flux.
You can use pretty much any torch you want, heck ive even used a cutting torch on castings! OH and OA can both be used with great results. If anyone has any specific questions feel free to e-mail me firstname.lastname@example.org

The Allstate flux you use is pretty much the same as the old Oxweld Alumaflux I believe. Oxweld was a trademark of Linde...then L-tec...then Esab. And then Esab bought Allstate. You can't tell the players without a program..
Aaron, again nice work...that's old school stuff bro!Rich Ferguson
