it switches to half power when not used for a while, then ramps up to temperature when picked up.
Auto power-off is standard on the Weller units, and is something I never thought would be useful. But having returned to my workstation after a couple days absence, and noticed the Weller power button still in the "ON" position (yet with a cold iron), I've come to appreciate such things.
Tin isn't exactly non-toxic either, although it doesn't act as such a potent neurotoxin as lead does.
The only real danger from lead while soldering, is getting it on your hands from handling the solder, and then neglecting to wash it off before touching your face. The toxic fumes from flux are a much more serious consideration.
Weller, nowadays, are crap, at least the lower-end stuff.
Dunno. The standard WES50 station here has had zero issues, and both of the old "standalone" Weller irons from my youth still work exactly as they did when new.
Cheers
