Weller soldering Iron

Hey, VHSers
I have noticed that the Weller soldering irons have been mistreated.
I have left out two of them and locked out the temperature control.
Right now, they are set to 700℉ and 750℉ for leaded and unleaded solder respectively.
They are labeled clearly as such on the side of the units.
Please take good care of these babies, they are expensive.
