soldering with 400C :popcorn: when tip is tarnished it wont take solder even with 400C and hot air wont help either |

Weller seems to disagree: https://www.mouser.com/pdfdocs/WellerSoldering.pdf --- Quote from: page 5 ---In order to raise the temperature of solder above its melting point, soldering tip temperatures are usually set between 700°F and 800°F. --- End quote --- I keep mine set at a smidgeon under 750°F (399°C). The only time I have ruined a tip was when I accidently left it on overnight. |

--- Quote from: page 3 ---Insufficient tinning when working with high temperatures over 665 F (350 C) and after work interruptions of more than one hour. --- End quote --- use 250 C for 60/40 and sensitive boards pb free higher soldering and desoldering is not the same |
