It seems to work well that way in the experimenting I've done.

I'm surprised, but if you say that it has worked for you then I'll
just have to remain surprised.

In general, getting the solder to wet both the tip and the work is the
essential part of transferring heat to the work. Heat transfer without
wetting is much poorer and is quite often insufficient for the job.

That is indeed what happens when a copper tip goes dry. The oxide film
seems to be a very effective barrier to the heat transfer. By
comparison, with Aluminum its oxide is only molecules thick and good
metal to metal heat transfer occurs at the slightest application of
pressure. From my experience, it did work well for desoldering but
I'll have to experiment soldering with a thick Al tip. Maybe a
slightly different method can be made workable, in contrast to the
usual soldering common sense of wetting the tip and the work.
