autocast universal

230 Casting System Operation of the autocast universal Stand 1.9. 03 B 25

Non-precious alloys are generally

melted at 50% inverter power.

Small amounts can be melted from

30% on up, larger amounts with

a maximum of 65% inverter power

(vgl. 29–32).

Precious metals are generally melted

with 15% inverter power.

Small amounts can be melted from

10% on up, larger amounts with a

maximum of 35% (see 29–32).

• Preset the inverter power with the rotary switch “POWER”.

• After stocking the machine with alloy and positioning of

the ring (see B17) press the “START”-button.

• ➯ The pressure-respectively time – controlled process

of melting begins. Pressure- and vacuum-values can be

observed during the whole process at the pressure

gauge (see B21).

• As soon as the arch ignites, the power can be readjusted at

any time by turning the rotary switch to higher or lower

settings.

• After all ingots have completely coalesced, press the

“CAST” button.

After the electric arc has ignited, the

melting process can be monitored

through the darkened viewing

window. At low output settings, the

second darkened window can be

pushed aside, thereby allowing

better visual control of the melting

process.

In case of non ignition of the arch the

melting process may be interrupted

by pressing the “STOP”-button, or

by turning the main switch. Check

contact of the crucible electrode to

the alloy!
