Risk of damage to property and production disruption
If you dry the atomizer incorrectly or incompletely, it will soil faster and
more intensely, especially the electrode rings and the electrode tips.
Paint particles accumulate faster on wet spots on the atomizer. These
paint particles can transfer onto the work piece to be painted (e.g.
bodywork, bumper).
Wet spots can lead to leakage currents. This can lead to massive high
voltage interference. The system controller will then turn off the high
voltage.
By all means dry the atomizer carefully after cleaning.
Dürr Systems generally recommends to paint at high voltage. Where
appropriate, voltage or current must be adapted to the conditions
during painting.
If spots must be painted without high voltage, make sure that the
electrodes are absolutely clean during the subsequent high voltage
painting. If necessary, you have to clean the electrodes before
painting with high voltage.
