Subject: [CR] Brazing with Cadmium Silver Alloy


Hello folks, my grandfather was a machinist and fabricator for many many years. He recently gave me three big rolls of silver brazing wire. Being a student, finances are very tight for me, and silver solder is very expensive, so enough free silver to do more than a few frames is great. The problem is, the stuff looks to be quite old as the tag is very yellowed with age. The tag says "Warning! Contains Cadmium." I of course dont have a fancy shop with a pro ventilation system. Is there any safe way I can use this stuff? If I did my brazing outside would I be ok, or do I need more ventilation? I suppose I could rig up an old gas mask (cheap at the local surplus) with a long hose for fresh air, but I imagine this would get hot and annoying. Any input on brazing with Cadmium Silver Braze would be appreciated. Thanks!
