Operation Guide

Fluid Supply/Settings

During the sales process, your DUX representa-

tive will help you choose the proper tip size and

fluid pressure for your application. Due to the

efficient nature of the DUX gun, this flow rate

is likely to be 15-40% less than your existing

spray gun. However, if changes are made to

your production speed, coating type, or desired

finish quality, it may be necessary to use a

different fluid tip size or alter the other settings.

If you are using the DUX gun for the first time,

or have recently changed your operations, we

recommend the following steps.

First, identify the flow rate of your existing spray

gun to serve as a benchmark. To do this, turn

off the atomizing air at the air regulator and

trigger the gun into a beaker or measuring cup

for 15 seconds. Multiply the resulting volume

by 4 to calculate your flow rate in ounces or cc

per minute.

Next, because DUX guns are more efficient, we

recommend you choose a fluid tip that is one or

two sizes smaller than your existing gun. Also,

because the fluid control micrometer knob is

designed for very small adjustments only, we

recommend you begin with the fluid micrometer

set at the 4A position – which allows maximum

flow.

PLATINUM PRESSURE FEED

With the atomizing air turned off, trigger the

DUX gun over a beaker and use your fluid regu-

lator to adjust the fluid pressure. Regulate your

pressure so the fluid stream arcs approximately

8" from the tip of the gun (see Figure 4 ).

If you apply too much pressure at the regu-

lator your fluid stream will be much too fast.

Proper atomization may be difficult under these

conditions.

Test Spraying

Proper operation of the DUX Pressure Feed

requires the trigger handle to be pulled fully to

the rear of the spray gun while spraying. This

ensures uniform spray patterns and consistent

mil thickness.

Spray a test pattern and evaluate the finish

quality. Increase or decrease the flow by

increasing or decreasing fluid pressure until the

desired results are achieved. If necessary, small

incremental adjustments of the DUX fluid control

knob can be made. When the optimum results

are achieved, record the setting for simple future

setups.

Figure 5: Fluid Micrometer Markings

The markings on the fluid control knob (shown

in Figure 5) correspond to 0.1mm of needle

travel when the trigger is fully pulled (e.g., rotat-

ing the control knob from A to B increases the

needle travel by 0.1mm).
