Used to be we didn't have fancy temp. controlled solder stations.
When my day job was as a bench tech and I had a soldering iron going pretty much all day, I built a temp control switch.
The iron was on full or half. When I didn't need it I switched to half, when I did need it, it heated up from half to full pretty quickly.
I built this into a box. The iron plugged into the box, the box plugged into the wall outlet.
Inside the box was a diode (sized to handle the load) in series with one side of the A.C. line.
The switch simply bypassed the diode for full temp operation.
With the diode in circuit, you only got half wave A.C. going to the iron.
I didn't go through tips nearly as fast.
