Ive done business with these folks before. They will often take
significantly less if the item doesnt sell on Ebay.

The seller of this EDM states: "This system appears to be in fair to
good cosmetic condition but has not yet been tested." No statement
they intend to do so.
In straight language I think this means "As is". This means they
have no firm idea (at least no guarentee) this machine will work.
This, of course, is not uncommon.
Since you seem to know something about these folks do you feel they
would take the machine back if it should prove too expensive to
refurbish? Or perhaps offer to compensate after a certain amount of
money has been spent? Or would they allow testing "on-site"? Most
folks would rather not get left "holding the bag" any more than the
machinery dealer would.

Its a fair amount of money..so give her a call and ask. It cant hurt a
thing.

"Pax Americana is a philosophy. Hardly an empire.
Making sure other people play nice and dont kill each other (and us)
off in job lots is hardly empire building, particularly when you give
them self determination under "play nice" rules.
Think of it as having your older brother knock the **** out of you
for torturing the cat." Gunner
That's a clean little machine Mark. In 1978 this was the state of the art
in sinker EDM power suply technology.
If it is 100 percent it's worth the asking price but if it needs any work at
all it's not worth much more than a grand or 1,500.00 at the most. The
transformer, BTW, is in the lower part of the magnetics cabinet and the
little box on top of it is the microfinishing power supply/servo control set
up.
It looks like a 10 Amp (current to the electrode) supply with both high
(180) and low (90) voltage. That means you can do "no wear" roughing. It
could be 25 amps but I can't tell from the photo's.
You have to be careful with these machines if you do because they will
actually build material on the electrode if you aren't careful when you run
no wear. When that happens you end up with some really nasty DC arcs. Big,
deep, nasty holes blown in your part.
The flush unit also has both pressure and suction which is very handy. It
takes suction to get the best finishes because your spark gap is usually
nearly zero. The gage on the tank is the gage for both.
These things usually have a base that everything but the pumps and tank are
mounted to/on. I dont see that in the pictures. You could bench mount the
thing pretty easily though. This would definitely be something cool to have
for gun porting and other home shop applications.
