Preparing the spray gun
Caution
The distance of the installed spray guns to each other
must be at least 300 mm
.
•
Fit the spray gun to the hanger and fasten both, for example, to the gun mounting on the
reciprocator.
•
Connect the spray gun to the high voltage generator using the electrical cable
E
.
•
Connect the hose for the powder feed
P
to the spray gun.
•
Connect the hose for the atomizing air
A
to the spray gun.
Hint
Using a Wagner powder injector and a suitable control unit, it is possible to
automatically blow out or purge the angled spray gun each time prior to switch off.
3.3 Grounding
For safety reasons, the
spray gun
must
be properly grounded. This occurs through the gun
mounting.

Good grounding of the
workpiece
is also necessary for optimum powder coating.
A poorly grounded workpiece causes:
•
dangerous electric charging of the workpiece
•
back-spray onto spray gun and user
•
uneven coating
•
very bad wrap around
Warning
Sparks between workpiece and conveyor hooks (hangers) can occur if
hooks or other hanger parts are not completely cleaned!
These sparks can cause heavy radio frequency interference.
