Just one big one that gets hot fast. It has to be in and out quick. A
deft touch with the 225 watt Weller will do both the barrel and the
tip. However when soldering the barrel there is a lot of mass that has
to be heated hot enough for the solder to flow. The problem usually is
not enough heat instead of too much. If the gun/iron doesn't get hot
enough to melt the solder quickly the barrel gets so hot overall it
melts the dielectric before you can solder the braid.
