4 DESCRIPTION
4.1 AREA OF APPLICATION, USING IN ACCORDANCE WITH THE INSTRUCTIONS
The electrostatic spray gun can only be used with the control units VM 2000 or VM 200.
4.1.1 WHAT KIND OF SPRAYING MATERIAL CAN BE APPLIED
•
Paints containing solvents of the explosion class II A.
•
Enamels,primers,textured paints etc.,which have a specific resistance of > 50 kΩ (accord-
ing to the WAGNER or Ransburg scale).
•
The effectiveness of the spraying action is always dependant on the composition of the
paint being used, e.g. pigments or resin.
Note
With very highly conductive materials or those with a very high electrical resistance, the
electrostatic effect does not work as efficienthly. The relationship between the values of
the high-voltage (kV) and the current (µA), shown on the HVM 2082, denotes the charging
capacity of a spray material.
High kV-value, low µA-value (no wrap around) = Paint with too high el. resistance.
Low kV-value, high µA-value (no wrap-around) = Paint with too low el. resistance
In the event of application problems, contact your WAGNER branch and the paint manu-
facturer.

4.4.2 FUNCTIONS OF THE GUN
The trigger can be used to activate, one after the other, the various functions of the spray
gun.
AW = Max way of trigger
LM = Air open
LE = Air open and electrostatics activated
LO = Air open and elektrostatics activated and
material valve open
•
An increase in the tension needed to pull the trigger back
will be felt at the position where the material valve opens.
•
in order to overcome Faraday cages in corners, the high
voltage can be switched off by flipping the HV switch (C)
down
•
The supply of the flat jet air is adjusted by means of the

4.5 AIR ATOMIZING SPRAY PROCESS
4.5.1 ROUND AND FLAT JET
In this process,the material (paint) is fed to the tip with low pressure at approx.0.05-0.2MPa;
0.5-2 bar; 7-29 psi.The atomizing air at approx.0.25-0.4 MPa;2.5-4 bar; 36-58 psi produces a
soft jet, which largely eliminates the problem of overlapping boundaries.
4.5.2 ROUND JET
The jet is cone-shaped.
4.5.3 FLAT JET
The spraying angle can be changed by adjusting the„fan air“. Depend on the material and
the output, a large range of tips and air caps are available to suit your needs (see para.
9.1).

4.5.4 ELECTROSTATIC EFFECT
The spray gun produces an electrostatic field by means of the high voltage electrode. As a
result,the particles of paint, which have been atomized by the spray gun,are carried to the
earthed object by kinetic and electrostatic energy where they adhere, finely distributed, to
the object being sprayed.
