The acetylene-oxygen is almost too hot for brazing small piping...use a short flame and a smaller tip on this stuff. Especially on piping smaller than 1/2 inch. I use the copper phosphorus flat rods on everything I can. It's a lot cheaper than the sta-silv and is self-fluxing. With the sta-silv, you have to use flux or your joints will tarnish and be brittle.

Do not use tin (plumbing/electronic) solder on any of the refrigeration circuit at all! It isn't strong enough to withstand the high pressure and vibration. It will taint the correct metals with oxides of lead and/or antimony. Keep that stuff for water pipes and electrical connections.

Good luck and take lots of pics.
