Speaking of desoldering, I have bench-news regarding
soldering.

A while ago I acquired a JBC HD-2B soldering station with T470A handle, some tips and original JBC stand for a half-decent price (270€) -given the corona-driven somewhat higher price level.
The station was delivered last week and today I had the time to modify it to accept C470 cartridges (JBC-tips, 48V) as well as C245 cartridges (24V). Nice thing is that the T470 handle accepts both types of cartridges.
After a little bodging and adding a 2pole DPDT switch I now have a manually switchable HD-2B soldering station I can use all types of C470 and C245 cartridges for soldering jobs demanding high and higher power/heat*.

I put the switch on the back right above the power inlet:

edit: There's a third connection involved with the 12V supply, that i didn't show: It might be a NTC sharing one connection with the 12V supply. Didn't modify.
edit²: *-compared to my T12 KSGER OLED-soldering stations with self-assembled alternative power supply.
The T12s have become my daily driver and have pushed out my Wellers completely.
