I remember when Joe (yanof) was telling me that he tried the cincon as a high side power supply for a charger, and it worked for low voltage, but not high voltage. Maybe I screwed up the isolated supplies. I did pick the cheapest possible line filter. I know for a fact that if I use a powerex isolated 15v-15v dc-dc converter, that an isotop mosfet switches just fine at high voltage. That's how I did the charger... So, I could try the powerex dc-dc instead of my isolated dc-dc. It may not be a problem with the soldering at all.
