Possible Causes
Remedies
Running / dripping
paint
Evaporation of solvents too slow
Use more lightweight solvents
Speed of application too slow
Slow the paint flow rate
Decrease the electrostatic
effect
Paint jet poorly dis-
tributed
Excessive paint flow rate
Decrease the paint flow rate
Increase the air pressure
Nozzle too thick
Use a smaller and thinner nozzle
Viscosity of the paint excessive
Dilute the paint
Air orifices partially blocked
Clean the spraying head
Little electrostatic
effect
Absence of high voltage
See indication on the control
module
Insufficient high voltage
Increase the high voltage
Distance too great between
spraying head and part
Control the

output voltage
Spray at a distance lying
between 200 and 300 mm
Part not grounded
Clean the hooks. Verify the
grounding of parts and the con-
veyor
Excessive ventilation
Reduce the booth’s suction flow
rate, while respecting current
regulations
Spraying pressure too high
Reduce the spraying pressure of
the product and/or air
Excessive paint flow rate
Reduce the paint flow rate
Generator short-circuit:
- by the exterior
Clean the gun exterior using a
non-conductive solvent
Take a new cover, one that’s
clean and dry
Generator short-circuit:
- by the nozzle needle line
Change both the cartridge and
the nozzle needle
Generator short-circuit:
- by the air channel
Clean the air channels in the
barrel
Generator short-circuit:
- by the product pipe
- and/or the cabinet
- or the insulating table.
Check the product hose
Check the insulation of the
pump and the paint tank.
Clean the insulating enclosure
and dry it carefully
The operator has felt
electrical dis-
charges when
touching the part.
Part not grounded or poorly
grounded
Verify the ground connections.
The user must wear gloves and
conductive shoes, in
