So here is a Stainless to copper union using soft solder and the right flux, now I will tell you that the stainless needs a fair bit of heat to get the solder to bond. I used quite a bit of paste flux on both bits and when the SS was just getting ready to glow, the solder dropped and bonded. You have to work your way around the area slowly and the solder will follow.
I warn you if your do this process do ALL your copper to copper joins LAST, or you will blow all your nice solder work copper on copper. The clean up was awesome and really saw no bad residue, just the darkened area that was heated and I hit that with steel wool and soap. It looks like shit after you heat it that hot but it cleans up nice and the nice thing is I used PROPANE ONLY. So if you use map or oxy propane your styling, I looked at the local welding supply for your ezi-weld 801 but it was not to be found. The welding supply said he sells a ton of this and it's cheap, 9$ here in Canada .
Note: (the flux is white ,like too much salt mixed with water to make a paste and the directions say you thin it with water)
