19. Reactivating the heating process
⋅ 180 degree before reaching the casting temperature or
after 15 sec. 100% performance is returned and
the metal gets liquid. Vacuum is again drawn.
⋅ Pls. don’t press any longer the Argon-key, so that the
vacuum is completely charged at the time of casting.
⋅ When casting vacuum must be fully charged!
20. Temperature control and
Casting
⋅ When the acoustic signal is perceptible or the
metal surface is ripped or the optical judgment is
corresponding to the judgement based on measurement
(with temperature sensor)
set step switch to step 2.
⋅
⋅⋅
⋅ Reaching the set temperature (acoustic signal) the
heating is automatically switched off,
therefore casting has to be performed immediately.
⋅ If you wish to continue heating, pls. press the key
„P“ and increase temperature with the arrow key
(3) and confirm with „P“.
21. Metal forming pressure
(automatically)
⋅ The lock pestle releases the bottom hole for casting.
After 0,5 sec. pressurization is activated
(Argon or compressed air). Vacuum stops automatically.
⋅ Red LED (18) is blinking.
22. Ventilating chambers
⋅ Set power switch to 0.
⋅ After 20 sec. set step switch to 0.
23. Opening chambers
⋅ Pull the locking lever in direction to oneself and wait until
the gage is declining to 0 bar. Unlock the chambers by
swivelling the lever to the left.
Now they can be swivelled open.
24. User pliers to take out muffle.
