Default Re: How to solder little stuff?

the core is the anti corrosion/ adhesion part of solder.. it can be flux, acid core or rosin core, or even solid... you wouldn't use solid core unless you were soldering a copper pipe and then you would also need flux.. Flux actully is a sheilding agent, just as you need in welding.. oxygen will cause a weld or a solder joint to not have good integrity, the flux sheilds and displaces the oxygen... then there are the cored solders.. Rosin core is special for high corrosion enviroments, and acid core can be used on indoor stuff.. not really sure on how to explain it.. they do perform the same function, but there intended applications are diffrent
