Central gas supply
The maximum permissible input pressure is 2.5 bar (36.25 psi). The APC
300 must be modified by a technician if a central argon supply is used.
Connecting argon cylinders
The input pressure at cylinder connections 1 and 2 of the APC 300 may not
exceed 4.5 bar (65.25 psi).
ERBE advises working with two argon cylinders with a volume of 5 liters
and a pressure of 200 bar (2900 psi). The APC 300 has been programmed by
ERBE to operate with this type of cylinder. If you wish to use other types of
cylinders, you must reprogram the cylinder data in the menu Argon gas
information under menu point Changing cylinder data.
