It is perfectly excellent, just make sure to fix with the right fuse
to not verschlimmbessern it (German expression for: attempting to
improve something but making it worse in the process).
Do you have a picture of the fuse ? Often, there is as well some
marking close to the power input or near the fuse connector.

If this press is in the order of 1200 W that means it would require a
>= 10A fuse. So the 25A sounds reasonable.
F25A250V means that it is a fast blow fuse for 25A. And all these
standard glass or ceramic fuses are rated for 250V (which really only
means that the filament is nicely insulated and that they won't arc
when they blow; lower voltage ones can do that, but would still
technically be safe to use if same amperage).

We have tons of fuses within Noisebridge, but it is not necessarily
clear if they have the right value. Lukily we have a search app to
help find the right component:
If within Noisebridge you go to
http://pegasus.noise:3000/search ( or http://pegasus.local:3000/search )
and type in "fuse" in the search box, you'll find a lot of instances
of parts. Unfortunately, they are mostly not yet sorted by value, but
you find the drawer number (something like ID:210 in the result boxes)
in the result page, so you can go to a couple of these drawers to find
if there are fuses with the right value.

Well, the device only operates at 120V, so it is much less.
