Thank you so much, im new to soldwring and this video really has helped me. Please 1 question i use wella solder with rosin inside the leaded solder and it always leave black marks on my tip. Is that ok.?? And would you say a brass sponge is also good please
It's my honor that this video can help you， Solder containing rosin or other fluxes will leave black marks on the tip after being heated at high temperatures. So, it‘s necessary to clean the residue of the tip frequently. a brass sponge is also good, but need to add water to it, otherwise it cannot withstand the high temperature of the soldering iron. Even so, the temperature resistance of brass sponge will be lower than that of high-temperature sponge, because of their different materials.

如果已經露出銅的部分是不是沒法修了？
是的，合金烙铁头，如果已经露出最里层的铜，就可以更换了，也没有修复的必要。因为，继续使用，铜会慢慢被锡溶解带走，最后变成一个空洞。
請問細砂紙是要用幾號的？
用400目的細砂紙，500目也行。
