Look at the Internet, they say that first dip a little rosin, and then put the electric iron, a layer of solder, you can use, but after I have stained rosin, or do not hang solder! What should I do? Request great God to advise!
Reach a certain temperature gently wear off the oxide layer in sandpaper, or solder paste in a corroded iron oxide layer is inserted on the head after the glue rosin can hang tin, iron temperature is too high will not hang, can control the temperature through plug the plug, the hope can help you
