Well, I got two connectors today for some 1/4" coppertubing. Used mapp gas. Used Alum oxide sandpaper to clean. Used flux. Used silver solder, no lead.
Heated it up, and could not get the solder to flow. Ended up burning up the connectors.
What am I missing? I had three tries, and I blew them all. I've sweated copper, and watched it done, but today was a real flop.
