Solder Lead Free - 100-gram Spool

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 led solder. Lead-free solder is a bit harder to use (does not flow as well).

**Mix:** 99.3% Sn / 0.7% Cu
