[morzh]

I put my Weller (a regular 40W soldering iron) on High (close to 800F), unsolder the braid, then take the socket wrench and, having really heated up the bold cap (when all the solder is liquefied) quickly put the wrench over the cap to push the solder off as much as possible (it freezes almost on contact) and re-form the cap, so it can be screwed and unscrewed.

Then after everything is done (cap is cleaned, grommets are replaced) and re-assembled, I put the braid on and solder it using the same temp settings for the iron and lots of Non RoHS (tin-lead) solder.
