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.
I have used this brazing rod and extra flux, is that what you are suggesting. I have used it on steel. The can of flux is the same as the white flux coating on the rod. When the braze rod is hot you dip it in the can and the flux sticks to the rod. I find that the extra flux makes it easier to braze.

I will practice using this on copper.
