Structure and function
OptiGun 2-A(X) (GA02) Automatic powder gun
High voltage generation
The OptiTronic control module supplies a high-frequency low voltage of
approximately 10 V eff. This voltage is fed through the gun cable (
11
) and
the gun plug to the high voltage cascade (
4
) in the shank of the gun.
In the high voltage cascade (
4
), the low-voltage is high-transformed in a
first step (
c
). This primary high voltage is subsequently rectified and mul-
tiplied in the high voltage cascade in a second step (
d
), until the required
high voltage is attained at the end (approx. 100 kV). The high voltage is
now fed in the spray nozzle to the electrode (
e
).

High voltage generation
Circuit
The OptiGun 2-A(X) Automatic powder gun is switched on and off by the
OptiTronic gun control unit.
The control unit allows also the adjustment of low voltage, powder flow
and rinsing air to the gun.
Powder flow and rinsing air
The rinsing air, used by the vented spray nozzle, is connected with its
designated connection on the rear of the gun control unit (see operating
instructions of the OptiTronic powder gun control unit).
Powder flow and rinsing air
The functions of the spray nozzles are described in the following chapter.
