Requirements for the protection-gas supply
For operation, the protective gas must fulfil the
following minimum requirements:
_ Argon 4.6 (or higher) from commercially availa-
ble cylinders (preferably 20 l)
_ Cylinder pressure 200 bar/2900 psi
When the left-hand manometer pointer
points to 0 or below, the cylinder is empty
and must be exchanged. The cylinder then
only holds a residual pressure of approx.
5 bar/72.5 psi, which may no longer be
used for the sintering. The furnace is
equipped with a compressed-air and pro-
tective-gas monitoring feature. When
there is no pressure on the gas side, the
furnace interrupts the sintering procedure
or the program will not start.

Compressed-air connection

To provide operation with air cooling, the furnace
must be connected to the compressed-air supply.
Requirements for the compressed-air supply
For operation, the compressed air must fulfil the
following minimum requirements:
_ Flow rate: 100 l/min (3.54 CFM)
_ Pressure: 6 bar (87 psi)
Requirements on air purity:
_ Solid contaminants: Class 3;
better than 5 μm for solids
_ Water content: Class 4;
Max. pressure dew point +3 °C
_ Total oil content: Class 2;
Max. oil content 0.1 mg/m

Establishing the compressed-air connection
▷ Insert the compressed-air hose to the stop into
the service unit.
Fig. 7
▷ Connect the other end of the compressed-air
hose with the compressed-air connection in the
laboratory.

Electrical connection

The electrical connection is to be made via a
socket outlet with earthing contact providing 220-
240 V and 50-60 Hz. This socket outlet must be
located close to the furnace and be easily accessi-
ble.
When using an extension cord or a multiple socket
outlet, do not exceed the respective max. electri-
cal load rating.
