Basic Soldering Guide: The melting point of most solder is in the region of 188°C (370°F) and the iron tip temperature is typically 330°C to 350°C (626°F to 662°F). Soldering Basics: Although tip temperature is not the key element in soldering you should always start at the lowest temperature possible.
