Measuring the Argon Flow Rates

The argon gas flow rate settings should be adjusted when switching between different fiber diameters.
The flow rate settings are set in the splice file.
To check and/or calibrate the argon flow rates:
Ensure the system is on and the regulator is set to9 – 12 psi.
Remove the filament assembly according to the directions given in Section 6.4: Filament Replacement
Procedure.
Insert the flow meter tube into the argon port as shown in Figure 33. Place the flow meter vertically on a
solid surface for the most accurate reading.
Select Argon Flow Rates from the menu bar. In the popup window, set the desired flow rate. Initiate the
purge using the Purge tool bar item. Wait 5-10 seconds for the flow meter reading to stabilize. Verify that
the flow meter measures the set flow value. Reset the purge flow rate to 2 l/min on completion of the test.
