- beeforpork 2y agoYes, it is flux (solid rosin). He vaporizes some with the iron and the smoke resolidifies on the contacts, so there is a very thin layer of flux to help with the soldering.
- Ecco 2y agoInteresting, I’ve never seen this before. How does it compare to regular gooey or liquid flux? Also how does it work? Just bringing a chunk of rosin next to a soldering iron would just vaporize the flux as seen on the video?
- xattt 2y agoMy grandfather who learned electronics work in the USSR worked with solid rosin. When you touch the iron with the rosin, it starts smoking like incense at a church (same stuff actually), but a small amount remains on the tip. You transfer this to the contact you’re soldering, dip into the rosin again, and then solder as usual.
