Not for you, but for those that might not get the point: the world of electronics assembly is really strange - it's like the whole past is present with us. It's 2021 and you can still buy a Weller soldering station with a knob for open-loop power (= heat) control for more than you'll pay for a cheapish station with closed-loop temperature control from any number of Chinese brands. (google "Hakko 936 clone"), Closed-loop temperature control is much superior to open-loop power control.
