Yea Iv'e f'd up my share in the beginning.
Iv'e been using the same $30 stick iron for 20 years, on at least my 5th tip, same can of flux too.... and I am on the 3rd 1lb roll of solder. Funny thing is people bring me their stuff to solder cause my joints are so clean.
Watch the good guys, practice, clean your tip a lot. tin tin tin

desoldering? on a simple esc post or wire just get it hot and shake it off.

nice post and thread
