Melting with
When you use carbon crucibles, there is no need to check the cycle count.
●
Carbon Crucible 1. Insert alloy into a carbon crucible and set the crucible into muffle in place to
press the MELT button.
2. Once Cast Temp is achieved and Hold Time is over, chime will sound to
notify that the alloy is ready for casting.

an amount of temperature set in the default value.

It is available to save the above increased temp in the program contents or

Melt Check
Press the VIBES button to slightly shake the muffle and to facilitate the
●
・
viewing of alloy melting situation.
Note When you check the alloy melting situation, we recommend you to wear safety
)
goggles and use the view glass provided. There is a slight chance that melted alloy
may splash out and viewing the alloy melted at high heat may affect your eyesight.
Melting with Argon Flow
Argon gas is useful for preventing alloy oxidation and effective for extending
●
the life of carbon crucible.
Double click the ARGON FLOW button and the argon nozzle engages to
・
inject argon gas from the tip of the nozzle into the crucible with alloy.
Repress the ARGON FLOW button once to disengage the nozzle.
Argon flow is adjustable with the knob on the Argon Flow meter to set
・
amount of flow. The flow amount of 1
2 liter/min is ideal.
～
Double click the LID button to draw out the argon nozzle but argon gas is not
injected. This function will come in useful for avoiding heat emission and for
shortening melting time. This will also help for longer life of carbon crucibles.
Casting Mode
■
Once the Hold Time is over, a chime will sound 6 times. Be ready to set
casting ring in place to start casting operation. Choose your option in advance
for the type of pressure for casting, compressed air or argon gas.
Place a casting ring on the top of muffle.
・
Note Place the ring on the center of the metal plate to fit with one of the circles on the
)
plate.
Note When the muffle inclines, return the muffle to vertical position before press the cast
)
button.
Close the chamber lid and move the locking arm down to lock.
・
Press the Cast button immediately.
・
Vacuum pump will work to create vacuum in the chamber.
・
When the programmed vacuum level is reached, the chamber inverts to
・
apply pressure.
While the chamber being inverted with cooling time over, the pressure
・
inside the muffle is released and the chamber returns to its original position.
Return the locking arm to the original position to open the chamber lid and
・
remove the casting ring and crucible.
