I think I did buy some - but can't remember using it. I found welding ally with my MIG good enough for the simple stuff I needed.
ISTR it was more a form of brazing than welding anyway.
I have had a quick look but can't find any details (or the hardware, come to that. I've a feeling if it was brilliant, I'd have scanned the instructions and where to buy etc and saved them on here.
I forget the name, I also bought some on the grounds that it looked potentially useful, but couldn't make it work the one time I tried. (It was probably a difficult application, but I am pretty good at silver soldering ferrous metal).
