There is sort of a trick to soldering deans. Add a small amount of solder to both sides of the tabs, put a small amount of solder flux on the side that you will be attatching the wire to. With the pretinned wire in place, apply the soldering iron to the other side of the tab, and there should form a continuous bond between the wire and the tab after the flux sizzles and boils away. Works every time, even with 10 gauge wire.
