For this type of work, I use the 900M-T-2LD tip. It doesn't have as much mass as the other one, so it won't overheat your joints as fast. Still, with good soldering technique, you should be able to use either tip.Originally Posted by just strum
Here is another recommendation: get a pair of locking hemostats. They're like $2-$3 at army navy surplus stores. Clamp these on to whatever you're soldering to act as a heat sink.
