• Coating smaller workpieces e.g. small profiles too much spray
material is lost. In this case the amperage should be reduced to an
adequate level.
5.4.3 Changing spray capacity
• Turn regulation screw (C) at spray device, until throttle valve is half
way opened.
• Set speed of wire feed via the step switch wire feed (7) as follows:
Step 0 = OFF
Caution!
Never switch wire feed step switch while spraying.
Make sure the correct step is chosen.
Otherwise the pull drive at the spray device can be damaged
in case of long operating period (if wrong step is chosen).
• Start spray process.
• Turn regulation screw (C) slightly, until the ammeter (5) shows the
desired spray capacity.
(e.g. 200 A for Zn-wire with chosen step 1)
• Push the OFF-button (A) at the spray device.
• The system can be started again; it is ready for operation.
5.4.4 Setting-up atomizer air pressure
• The atomizer air is adjustable via the pressure regulator (9).
• The pressure of atomizer air can be set between 3,5 and 6 bar. For
adjusting the pressure pull out the regulator button slightly, adjust
to desired pressure, and push down the button.
• The correct atomizer air pressure will be determined by the requi-
red fineness of the coat and the application.
• Coarse spraying particles result in a coating with a high metallic
content. This will have a coarse surface texture, however.
• Fine particles, atomized under high air pressure, on the other hand
result in a fine surface texture. They are less well-suited to the
subsequent soldering work, because they have a higher oxide
content.
