Description
Introduction
The Nordson Vantage manual electrostatic porcelain enamel (PE) spray gun
electrostatically charges and sprays porcelain enamel (frit) powders.
The spray gun is used with a Nordson Vantage control unit, which supplies
low-voltage dc power to the voltage multiplier in the spray gun. The
multiplier generates the high electrostatic voltage needed for powder
coating. The operator adjusts the electrostatic voltage at the control unit.
This voltage generates an electrical field (corona) around the gun electrode.
As the powder particles are sprayed through this field they pick up an
electrical charge and are attracted to the grounded parts in front of the
spray gun. The current at the electrode is limited to safe levels by a resistor
installed between the multiplier and the electrode.

Introduction (contd)
See Figure 2-1. The spray pattern is controlled by the electrostatic field, the
shape of the nozzle used, and air velocity. Powder is supplied to the spray
gun by a porcelain enamel powder pump. The pump uses compressed air
to draw the powder from a feed hopper, atomize it, and force it through the
feed hose to the spray gun.
There are no controls on the spray gun except the trigger (8) and the
pattern adjust sleeve (4). Voltage controls and powder pump air pressure
regulators are housed in the control unit.

Installation
WARNING: Allow only qualified personnel to perform the following tasks.
Follow the safety instructions in this document and all other related
documentation.
Feed Hose, Cable, and Air Tubing Connections
WARNING: All electrically conductive equipment in the spray area must be
grounded. Ungrounded or poorly grounded equipment can store an
electrostatic charge which can give personnel a severe shock, or arc and
cause a fire or explosion.
1. See Figure 3-1. Connect the feed hose (1) from the powder pump (2)
outlet to the hose adapter on the underside of the powder inlet body.
Pinch the hose and snap it into the hose bracket at the base of the

NOTE: Keep the powder feed hose as short as possible. The hose should
not be more than 12-m (39-ft) long. Longer lengths may cause uneven
powder flow.
2. Wrap spiral-cut tubing around the feed hose at the pump outlet and
where necessary to prevent the hose from kinking and blocking the flow
of powder.
3. Connect the gun cable (8) to the GUN OUTPUT receptacle at the rear of
the control unit (9). Secure the cable to the control unit with the
retaining nut on the cable end.
4. Refer to Table 3-1 to connect tubing to the control unit, powder pump,
hopper, and air supply.
