1. Bonding
2. Wetting
3. Soldering
4. Prepping
Which of the following should apply when tinning stranded wire?
1. The strands should be thickly coated.
2. The strands should be visible under the solder.
3. The solder should wick up underneath the insulation.
4. A large blob of solder should form at the end of the wire.
Metals like aluminum and iron wet easily.
1. True
