I know for the shield I want to use a big high wattage iron with lots of thermal mass. However for the center pin I want to use a Weller WESD51 temp controlled iron. I'm just not sure what the ideal temp setting should be. Is 750F too hot? Something like 600 more appropriate? Obviously I want the solder to flow fast but I don't want the center conductor to get so hot that it starts to move around in the foam dielectric.
