NOTE: The air pressures given are average starting points. Pressures
will vary according to required film build, line speed, and part
configuration. Adjust the pressure to obtain the desired results.
2. Set kV and pump air pressures.
Air Pressure Setting Function
Flow Rate 1.4 bar (20 psi) Controls the volume of the
powder delivered to the gun
Atomizing 1.0 bar (15 psi) Controls the velocity and density
(powder-to-air ratio) of the
powder
NOTE: Gun air pressure is controlled by a fixed-orifice restrictor on
the controller’s back panel.
3. Trigger the spray gun. Adjust the flow-rate and atomizing air
pressures until you obtain the desired spray pattern.
In a quick color change system, the powder feed center purges the spray
gun internally during the color change process.
See Figure 4-1.
In a quick color change system, two powder feed hoses are used for
each gun: one for light-colored powders, and one for dark-colored
powders. The hose hanger bracket (2) has fittings (5) on either side to
hold either inlet connector with powder feed hose attached.
After the purge process has been completed, switch the powder feed
hoses using the following procedure.
1. Loosen the nut (3) from the inlet connector body (1).
NOTE: The nut will stay on the inlet connector/powder feed hose
assembly.
2. Remove the inlet connector/powder feed hose assembly (4) from the
connector body (1) and push it on the empty hose hanger bracket
fitting (5) until it fits snugly.
3. Take the other inlet connector/powder feed hose assembly from the
hose hanger bracket fitting and push it into the connector body until it
bottoms out.
4. Tighten the nut.
