Soldering iron working techniques

Flux is your friend - My old electronics teacher

shouldnt need extra flux, tin the wire FIRST with proper solder wire, it has, or SHOULD have, flux core(s)

Even though I didn't understand, I watched it until the end.

What did the put between the pins of the jack socket? The iron must have been hot to melt the solder so quickly.

What kind of flux are you using or what brand is it?
