7.1 Safety advices for operation
Caution!
Examine all consumables, insulations and hoses before switching
on. Check for damages and cleanliness, especially crucible, sealing
rod, die and insulations. Operate the system only when it’s free of
damages.
Warning!
Risk of burning on hot surfaces and hot metal
(until ~ 1500 °C). Wear always personal protective
equipment when you work with the machine.
Utmost caution during using graphite crucibles and
graphite moulds. The heat of these parts is only visible
when the temperatures are over 500 °C.
Danger!
Risk of burns. The surface of the bell can be very hot, depending on
the working temperature.
Danger!
Risk of burns. If metal is melted without the supply of protective gas,
can cause a flash fire or explosion when opening the bell.
Melt at temperatures above 500 °C always with protective gas. Use
as a protective gas exclusively argon or nitrogen.
Danger!
Burning risk by leaking hot metal at protective gas failure.
When protective gas failure of the sealing rod can no longer close
properly. Through a check valve, the pressure is maintained in the
lock cylinder. If pneumatically powered units operated after a protec-
tive gas failure, molten metal can freely leak through the die.
Press after a protective gas failure, no pneumatic units (e.g.: cylin-
der).
