ü To determine the Wave offset for a wave power of [1%]:
ü You have mounted the nozzle
ü The mounted nozzle has been installed and activated in the Data table solder
nozzle
ü A value of [1%] has been entered into the [Wave power] input field.
a) Enable the solder wave.
b) In the [Module tests] frame, click on the
button.
ð A solder wave height test is performed. As soon as the solder wave
touches the test needle, the [Wave offset] status indicator lights up green.
Wait until the solder wave height test has been completed.
c) In the [Manual movement] frame, click on the
button.
ð The solder pot is moved to the [Service] position.
4 mm
d) Check the height of the wave in the nozzle. With a 1% wave power of the max-
imum value, the solder should be in the middle of the nozzle, about 4 mm un-
der the upper edge of the top. In a narrow nozzle, the solder is drawn by capil-
lary action upwards to the sides, while this effect is slighter in a wide nozzle.

ð If the distance of the solder surface from the nozzle upper edge is less than
4 mm or the solder already overflows:
e) Open the solder nozzle table and slightly reduce the [Offset warm] value, for
example by 500.
ð If no solder cn be seen in the solder nozzle, or the distance of the solder
surface from the nozzle upper edge is more than 4 mm:
f) Open the solder nozzle table and slightly increase the [Offset warm] value, for
example by 500.
g) Save the entries and check the height of the wave in the nozzle again.
h) Repeat steps c to f until the solder in the centre of the nozzle lies approxim-
ately 4 mm below the upper edge of the nozzle.
i) Note down the [Offset warm] determined value, you will need it later.
ð You have correctly set the [Offset warm] value for a wave power of 1%.

ü In the [Settings Soldering unit 1 Solder pot 1] settings dialog, the [Wave power]
for the solder wave height test has been set to 75%.
ü The mounted nozzle has been created and activated in the Data table solder
nozzle
ü A value of [75%] has been entered into the [Wave power] input field.
a) Enable the solder wave.
b) In the [Module tests] frame, click on the
button.
ð A solder wave height test is performed. As soon as the solder wave
touches the test needle, the [Wave offset] status indicator lights up green.
Wait until the solder wave height test has been completed.
ð In the [Module tests] frame, a new value is now specified for the [Wave
offset]. This value was also automatically transferred to the nozzle table.
