Wow, did not know you COULD braze it.  I've seen it TIGed and MIGed and 
even that's tricky with good equipment.  It sucks the heat away from the 
weld so quickly, it's hard to get it hot enough.  OTH, beverage cans 
melt in campfires.

I think you need at least an acetylene setup.  Pre-heating to 400 or 500 
in the kitchen oven will help too.  Did you google it?  There are a 
bunch of articles out there on it.
