Soldering to copper pipe with a soldering iron sure is hard. I had to use a kitchen torch to keep the pipe hot, otherwise the solder refused to wet it! :(

Getting the copper pipe hot with the torch then tinning it prior to bringing in the wire seems to help a lot. :3c

Yes! This will do a great job. Scrub the pipe briefly with steel wool and ideally put on some pre-solder flux and you'll have water-tight joints. But as you just need electrical contact, standard lead solder and flux will do fine.
