overpressure
Possible reasons of losing vacuum:
1.)
O-Ring of vacuum chamber is not OK.
2.)
Flask top surface is not flat enough.
3.)
Silicon ring is missing or faulty.
4.)
Flask cylinder is not in ‘up’ position.
5.)
By using overpressure on the crucible
area you need 8 bars air pressure.
With 6 bars pressure the flask will
move down and the vacuum will be
lost.
6.)
Flask has cracks.
7.)
‘Flask’ isn’t selected in Program Set-
up.
