When I pre-tin, I prefer a tiny bit of extra flux agent, T.Are you not planning to use the solder infused with 2% flux? After I saw that video that Analog Dan made (thanks @ShamrockPat ) I asked a friend/colleague about it. This guy is an electronics tech and has been soldering every day at work for the past 40 years. He says that since the introduction of the solder/flux mix, he only ever uses separate flux to dip his brass wick in for de-soldering,
shorter time before flow I feel flux gives.
Liquid flux, cleaning agent, desoldering equipment, solder, and cleaning for soldering irons are what I’ll get next week.
Tonight I soldered wires to a battery tube.
