ARGON FLOW Button
Click the button rapidly twice to engage the argon gas nozzle and flow argon
gas during melting. Argon flow meter checks the gas flow amount.
LID Button
Click the button rapidly twice to engage the argon gas nozzle without the flow
of argon gas. Press the button once to disengage the nozzle.
CAST Button
Press the button after locating casting ring in place to start casting.
ARGON AIR Button
Press the button to choose between argon gas and pressurized air applicable
・
for casting. Double click the button to change to either Ar. or Air pressure
mode to avoid mistake in operation.
Argon pressure will prevent alloy from oxidation and will help you grind cast alloys
in shorter time.
CAST CYCLES Button
Press to show the casting cycles used of the ceramic crucible inserted in
crucible counter. The number of casting cycle is shown on the 2 digit display.

Preparations before Use
■
Power Requirement We recommend you to use the proper power voltage described in the main
●
specifications of this unit.
Location & Environment
Set up the unit on the center of a flat stable table
●
・
Keep the unit away from walls and other equipment
・
Note We recommend you to set up your furnace 8 inches off the surrounding walls and
)
5 feet off lab ceiling and do not place any thing flammable near the furnace.
If the appropriate distance from each periphery can not be secured, we recommend
you to place the insulator on each wall and ceiling to prevent fire.
Connect air pressure hose provided to the

30 cubic meters/hour at the pressure of 0.8MPa 116psi . We recommend you to
(
)
use our optional pressure regulator provided to avoid occasional miscasting.
Note Keep the hose length as short as possible to decrease the flow resistance in the

piping.
Plug the vacuum pump to the pump power outlet as shown on the right

drawing. Connect the vacuum pump hose to the hose inlet.
●
Note We recommend you to use our optional vacuum pump, DDP-40 or KD-VP. The use

of a vacuum pump other than that of KDF brand may not work effective machine
functions and may even cause machine malfunctions.
