Oh yes I did!
That is a vintage 1993 Panasonic AC/DC 300 Amp TIG welder and water cooling pump for said TIG welder.
Just a tick over $1800.
Believe it or not but with only argon gas, not helium, this unit is supposed to be able to weld 3/4" thick Aluminium, that is quite something.
A short write up about this welder >>Here<<
If these guys Aerojet/Rocketdyne used this welder to weld up stuff for rocket engines, I figure it should be good enough my my projects!
Yes it is three phase, and yes it is large, but it should be the last TIG welder I need to own.
Of course now I have to learn how to TIG weld too.....
