Who knows how to solder two coins together? Either the front or the side. I haven't solder it for days, thank you
Solder coins?And as the solder iron melt in iron.....Place a small amount of solder paste on the weld and put it on the top
Coins are alloy. There may be no tin metal component. The surface shall be chromium and not weldable.. It may require argon arc welding or silver welding to weld
Coated with solder paste, welding can be, pay attention to use good solder paste, with high-power electric soldering iron, welding time a little longer, in fact, very easy to succeed, because I have welded
