Vintage Weller stations - opinions / tests / tips

[mt777]

I like vintage computing and want use tools for my hobbyist purposes.
Recently acquired a few old Weller machines but I need help to ressurect them to working state. Even with manuals, some configs are confused to me.

1. WELLER DS701EC

Double station with desoldering gun (DS21). Seems works as expected after replacing filters and glass. I wait for new tips to do tests.
Drawback: 50W only




2. WELLER WDD80V

Desoldering station without vacuum. Gun DS80 (not DSX) so tips are the same like for older version.
More power: 80W. Handle is very hot (uncomfortable)

Problems/questions:
1) What I need as external air source? with reasonable size. I couldn't find photos on web of full set. Every selling unit is without providing air solution... Temporarily I connected as air pressure source to DS701EC
2) Comparing to DS21 gun: diameter hole is much smaller than DS21 (see attachments). So vacuum is worse or maybe it is compensated by stronger external air source?
3) What is difference between DSX80? Are new tips style better (DX serie) than older DS ?




3. WELLER AG701

Hot air station. There is reaction for pedal.
I have 2 different guns but don't understand them well.

Problems/questions:
1) One gun is with DIN ending. So it means no air but what is purpose of it?
2) The second gun is for air source? but don't understand innerside 3pin cable connector?




Also own opinions of these machines are welcome.
