As Richard said, you want 63% tin, 37% lead, which gives the lowest
melting point (adding more tin actually makes it melt higher) and the
smallest plastic range (making cold joints less likely). Also called
eutectic solder. A quality brand will also contain very small amounts
of other metals (like bismuth) to improve the quality of the joint
Rosin core is also a good idea, it helps the solder 'wet' the wire.
IMO Kester 'Multicore' solder is about the best there is, but I use
Alpha (mostly because I haven't finished the several pounds I inherited
when a former employer closed an assembly line).
