The pic wasn't my work, just an example of what I was trying to do. I'm familiar with tinning, my biggest problem was lack of flux.
It was always explained to me that flux "helps the solder flow". Didn't know until now that the flux actually corrodes the top layer of oxidation off of the metal when it heats up, allowing for a pure(ish) bond (and the solder certainly does seem to flow onto a wire when this happens, but the reason WHY was what I really needed to get it through my thick skull).
Just broke my personal record for number of consecutive days without dying!
