I've never soldered or worked with bare metal before and thought this might be a good pedagogical project. I bought the a Weller WLC100 and some SchmartSolder. My first attempt I set the unit to 5 (max power), waited a minute, set it to 3, waited a minute and pressed the tip against the solder. It went up in smoke instantly, I'm assuming it is too hot. I brought the temperature down to 2 and it still burnt off, though not as quickly. Any suggestions, what temperature (1-5 number) should I be soldering at? Also. how straight do the breakway headers have to be when soldered on? I assumed very straight, but I had a hard time holding them in place, is a third hand tool necessary? Also is the board ruined? Did I "burn away" anything? Thanks, I thought this would be the easy party.
