A soldering tip is used in soft soldering to transfer the heat energy from the heating element of the soldering iron to the joint to be soldered by means of heat conduction and to create a solder joint by adding solder. The actual thermal bridge between the tip and the solder joint is the liquid solder that wets the soldering tip and touches the joint to be soldered (contact soldering). If a soldering tip is no longer wettable, no heat can be transferred. Most of these are electroplated copper tips in various geometries.
