Faults
Possible causes
Remedies
Paint running
Solvents evaporating too slowly
Use lighter solvents
Spraying applied too slowly
Reduce paint flow
Increase spraying air pressure
Reduce the electrostatic effect
Paint spray overloaded
in middle
Paint flow too high
Reduce paint flow
Increase air pressure
Nozzle/tip too large
Use a smaller nozzle/tip
Paint viscosity too great
Dilute paint
Air holes partially blocked
Clean spray head
Insufficient electrostatic
effect
High voltage power not on
See display on control module
High voltage power insufficient
Increase high voltage power
Distance between spray head and part
too great
Check Airmix® output voltage
Spray from between 200 and 300 mm
away
Part not grounded
Clean hooks. Check grounding connection
of parts conveyor
Excessive ventilation
Reduce paint booth air extraction rate,
ensuring the applicable regulations are
still complied with
Spraying air pressure too high
Reduce spraying air pressure
Paint flow too high
Reduce paint flow
Product resistivity too high
Reduce product resistivity to obtain
ρ
<
500M
Ω
.cm
Control module short circuit:
- external
Clean outside of the spray gun with a
non-conductive solvent (
ρ
> 15 M
Ω
.cm)
Use a new, clean and dry case
Control module short circuit:
- via needle assembly
Replace seal cartridge and
needle
Control module short circuit:
- via air channels
Clean the air channels of the barrel
Control module short circuit:
- via product hose
Increase the resistivity of paint so that
ρ
>
5 M
Ω
.cm
Operator gets electric
shocks when touching
the part
Part not grounded or poorly grounded
