▷ Connect the other end of the gas hose to the gas
regulator/gauges of the protective-gas cylin-
E N
der. For this, insert the protective gas hose into
the push-in connection by turning and pushing
in, until the resistance of the seal is overcome.

▷ Completely open the right-hand valve on the
pressure reducer.
To check the gas hose's tightness against leakage:
▷ Open the gas cylinder and gas regulator/gauge.
▷ Widely pivot/move about the gas hose at the
gas regulator/gauge.
There should not be any hissing noise whatso-
ever.

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
2.
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
1.
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 m for solids
_ Water content: Class 4;
Max. pressure dew point +3 °C
_ Total oil content: Class 2;
Max. oil content 0.1 mg/m
