4.1 Argon gas bubbler
An argon gas bubbler is installed on the argon gas exhaust line. The water in the
argon gas bubbler works as a resistance to suppress the pressure fluctuation in the
spark stand.
Keep the water level in the argon gas bubbler at 8 to 10cm. Replace the water if it is
heavily contaminated.
After adding or changing water in the argon gas bubbler, recalibration is necessary.
For details, see the table shown in "5.2 Maintenance Flow" and follow the specified
