Oops, sorry, I was refering to the plug on T4P's unit. Yours has a crappy DIN connector, just like my brand new and stylish (not overly cheap either) Hakko soldering station at work, as well as all of our old and horrible Weller units.

The factory DIN connectors never lasted the life of the old Weller units, so it's annoying to see them still being used as some kind of standard ~20 years later in new "premium" products.
