Solder & Torches
Jewelry Soldering Supplies
There are a several different forms of solder; solder wire, rosin core solder wire, acid core solder wire and prefluxed solder paste. Rosin core solder wire is used for soldering electronic circuit boards. Acid core solder wire is used for joining pieces of metal together such as jewelry making.
I use different mediums depending on what I am trying to accomplish. The prefluxed acid core solder wire is my favorite for most applications. But if I am trying to get in between two pieces of metal, such as a metal base and an ear clip, I prefer to use the solder paste.
If the solder wire is not prefluxed or you are using solder pellets than you must apply flux to the metal before the solder.
