I use chipquick 63/37 "no clean" rosin core solder............very thin.
A thick solder may require you to overheat the "tab" you are soldering to and possibly damage a pot.
You cannot damage a fullsize pot with normal electronics soldering equipment and methods
Why do you keep posting nonsense? Of course you can overheat a pot with standard iron.

There are a few pots around that use plastic or nylon parts---VERY easy to deform or melt with bad technique. Soldering to the back of a pot essentially turns the whole thing into a heat sink if you use the wrong temperature, wrong solder, or just suck at soldering.
