Electrostatic Voltage
Under no load conditions, the maximum voltage limit
for these spray guns is 100 kV. Some painting opera-
tions may require different voltage settings to obtain
optimum transfer efficiencies. If Faraday cage areas
are predominant on the item being painted, a lower
voltage setting would aid in coating these areas.
When not spraying, it is recommended to set back
voltage to 30-40 kV or off between target parts.
Sometimes, depending upon target carrier spac-
ing, higher setback voltages may be required. The
ramp-up time for the HP-404 cascade (0-100 kV) is
approximately 3 seconds.
The MicroPak voltage ramp-down works at a rate of
33 kV/sec.
> If target distance is less than 8 inches, an
arc could occur.

> If a 0 kV command is sent to the MicroPak,
a feedback fault will occur.
NOTE
Target Distance
The distance between the gun tip and the article being
painted should be 10-14 inches. Excessive distance
causes a waste of coating material and wrap back
(paint particles being deposited on the gun body or
the robot arm). At close distances the voltage at the
tip of the gun will be reduced, which decreases the
charging effect of the gun.
