Need some help soldering Binding posts.


I need to replace my posts on my speakers.I've an excellent soldering station
and will be using cardas solder.
All binding posts have a hole what is its function?
When applying the solder I've noticed I must use more and apply over a greater area,Is this correct?
Is it ok to use flux on the post and cable then solder?
Any advice.

Don’t forget to prepare the mating surface of the binding post before soldering by lightly sanding or wire-brushing. This, as well as a modest amount of rosin flux (never use acid flux) will ensure the solder “wets” correctly. This provides as close to a molecular bond as possible. And yes, wrap the wire firmly around the post, or double fold it over if inserting in a tube before soldering. This will give you the required mechanical integrity that is necessary for long term reliability. A good soldering iron or station with the correct (1/8” or larger) tip should be sufficient to heat the post and wire. My preference is the Weller WTCPS or WESD50.
