Are you an advanced user? Are you looking for something that could be used to a range of time that lasts between 6 to 12 months depending on your soldering for it? You’ve reached the right place.
This spool is a basic one that is lead free solder and it’s actually water soluble resin core, 2.5% flux, 0.031" gauge and 100 grams. However, don’t worry if you’re still a beginner in soldering, we have the leaded solder for you, order it and use it, since lead-free solder which is the one right here isn’t easy to use and it doesn’t flow very well.
Mix: 99.3% Sn / 0.7% Cu
