Technical explanations concerning high voltage and
spray current
Characteristic curves of Preset mode
The preset values for high voltage and spray current in the predefined
operation mode (Preset mode) are to be taken as reference points. The
modification of these values has effects on the characteristic curve of the
gun (see diagram). The operator can optimize the application within the
possible 3 ranges.
Characteristic curve of Program mode
In the user-defined operating mode (Program mode), the values for high
voltage and spray current are adjustable. The operator can optimize the
values for his application by utilizing the ranges below (see diagram).
Spray current (µA)
High voltage (kV)
