Description: This is your basic spool of lead free solder with a water soluble resin core. 0.031" gauge and 100 grams. This is a good spool for more advanced users that should last 6-12 months depending on how often you solder.
If you are just beginning to solder, we recommend you order the leaded solder. Lead-free solder is a bit harder to use (does not flow as well).
Mix: 99.3% Sn / 0.7% Cu

I was a little worried about using lead free solder after hearing how hard it can be to work with, but this stuff worked fine so long as your iron is hot enough (700° F), and you have a little blob of solder on the end of the iron whenever you try to solder something (the blob provides more surface area to transfer the heat).
