Ok. Thanks for the affirmation that the flux isn¡¯t the issue ?while using the jewelers loop, I found this. Mr. Ludwig, could this cause the overload condition? Somehow the wire got pinched or hit with the iron or whatever. I¡¯m not sure how I cut it but this is the only thing I can find that doesn¡¯t seem right. No idea how to change or fix this one if it could indeed be the problem ?
