Summary
This video explains why and how to tin a soldering iron tip to maintain its performance.
Highlights
Identifying a Deteriorated Soldering Tip
00:00:05
A soldering iron tip may show signs of deterioration, such as poor solder adhesion, black spots, discoloration, or a rusty appearance, indicating the tin coating is degrading.
The Purpose of Tinning
00:00:17
When the tin coating deteriorates, the tip needs to be refreshed by tinning. This process involves breaking down the oxide coating that forms on the tip.
Materials for Tip Tinning
00:00:30
A block of sal ammoniac is used, which generates ammonia vapors to disintegrate oxide layers and allow for tin reapplication to the tip.
The Tinning Process
00:00:42
Heat the sal ammoniac block until it generates vapors. Then, flow solder onto the tip to remove any formed oxides. Finally, wipe the iron on a wet sponge.
Result of Tinning

After tinning, the soldering iron tip will be clean, shiny, and ready for effective soldering.
