operating mode

When a probe is screwed into the direct welding holder, the
seal pusher presses the o-ring into the space between the steel
frame and the probe shaft. This seals the probe in a manner that
almost completely eliminates crevices and their associated risk of
contamination.
When the probe is loosened, the o-ring relaxes again. This lowers
the friction between the o-ring and the other parts of the assembly,
and the process is no longer sealed.
If this takes place while the process is still under pressure, the pressure
evacuation holes feature (see chap. 7.3.2), automatically comes into use.
