You have probably never soldered *without* flux.  The rosin core in
ordinary electronic solder is the flux.

The purpose of flux is to clean the metal that you're about to solder to.
The idea is that the flux melts and gives the metal a quick cleaning,
flowing just ahead of the solder.

BUT I hope that when you used a separate flux, you used a kind that is
suitable for electronic work!  The kinds used in plumbing (zinc chloride,
etc.) are not reliable, over the long term, in electronic gear.  They
have a nasty habit of continuing to corrode over the years.  This wouldn't
be a problem in plumbing, where the soldered joint is _big_, but in
electronics, a millimeter of crud isn't tolerable.
