4.
Turn on the air to the gun. Turn ON (I) the ES
On-Off switch (J).
5.
Spray a test pattern. Check the atomization. If
over-atomization occurs at minimum pressure,
adjust the atomizing air restrictor valve. If
atomization is inadequate, increase air pressure
or decrease fluid flow.
Note
Use the minimum atomizing air pressure
to extend electrode wire wear life.
Reduce the gun inlet air pressure or
adjust the atomizing air restrictor valve
(G) counterclockwise to reduce atomizing
air when the application allows.
6.
Adjust the fan air adjustment valve.
• Fully open the fan air adjustment valve,
counterclockwise, for the longest pattern.
• Turn the valve clockwise to restrict the fan air
and create a shorter pattern.
Note
Use the minimum fan air pressure to
extend electrode wire wear life. Reduce
the gun inlet air pressure or adjust the
fan air adjustment valve (F) clockwise
to reduce fan air when the application
allows.
7.
Spray a test piece. Examine the edges
for coverage. If wrap is poor, see
