Functional description
1. High-Voltage generation
The voltage generation module (Control module) supplies high-frequency low-voltage.
This voltage is conducted by the gun cable (
12
) and the gun connector (
11
) in the Support to
the high-voltage cascade (
4
).
This low voltage is stepped up (
c
) in the cascade (
4
). This primary high-voltage is subse-
quently rectified and multiplied in several stages in the cascade (
d
) until the required high-
voltage is attained.
The high-voltage is then fed from the spray nozzle to the electrode (
e
). See Figure 3.
When the high-voltage is adjusted on the control module, the intensity of the LED (
6
) also
changes. The user has the assurance that high-voltage is present and has control over this
function.

2. Powder flow and supplementary air
The supplementary air, serving as rinsing air, is connected to the gun, shown in Figure 4,
when air-cleaned nozzles are used.
The function of the nozzles are described in the applicable sections (see page 3).
