I work with Sn 63 Pb 37, 1.8% flux solder which has a melting point of 187C, however, in order to reliably melt it I have to set my FX888D soldering station to 350C. Do I have a problem with my soldering station?
I measured the tip of the soldering iron at 258C when pressing into the temperature probe on my multimeter. Why is there such a difference between the specified and measured temperatures?
The tip does have a bit of play on the heating element inside the iron - could this be the issue? Maybe I need a new heating element?
