Nozzle 1 is to be used alone
ü If nozzle 1 is to be used alone for fluxing:
a) Refer to the table. If nozzle 1 is to be used alone, enter number [1] into the
[mode] register.
ð If this data set is processed, the fluxer will spray with nozzle [1].
Nozzle 2 is to be used alone
ü If nozzle 2 is to be used alone for fluxing:
a) Refer to the table. If nozzle 2 is to be used alone, enter number [2] into the
[mode] register.
ð If this data set is processed, the fluxer will spray with nozzle [2].
Example of use
You can use this function if the two nozzles are connected to different flux material
containers: Nozzle 1 sprays flux A, nozzle 2 sprays flux material B.
ü If nozzles 1, 3 and 4 are to be used for fluxing:
a) Refer to the table. If nozzle 1, 3 and 4 are used, enter number [13] into the
[mode] register.
ð If this data set is processed, the fluxer will spray with nozzles 1, 3 and 4.

ü To assign the reference point to nozzle 1:
a) Activate the [Fluxer coordinates relate to nozzle 1] checkbox.
ð This action always assigns the reference point to nozzle 1. If, in case of an activ-
ated checkbox, values are entered into the [Endposition X] / [Endposition Y] re-
gisters, nozzle 1 is always moved to this end position; no matter how many
nozzles are available, nozzle 1 is always the reference point if the checkbox is
enabled.

ü To assign the reference point to another nozzle:
a) Deactivate the [Fluxer coordinates relate to nozzle 1] checkbox.
ð This action always assigns the reference point to the nozzle with the lowest
number according to the mode. Example: If mode [6] has been selected, the
reference point is assigned to the nozzle with the lowest number according to
mode 6, i.e. nozzle 2. If values are entered into the [Endposition X] / [Endposi-
tion Y] registers, nozzle 2 is always moved to this and position. Nozzle 2 is al-
ways the reference point.
ü Entering the spraying quantity:
a) Enter the [%] amount of flux to be sprayed into the [Spray amount [%]] re-
gister.
ð If a value is entered here, the corresponding amount of flux material will be
sprayed. If no value is entered here, no flux will be sprayed. The spray head is
only positioned.
ü Entering the spray time, spot and path spraying:
a) Enter the spray time into the [Spray time [s]] register.
ð If a value is entered here, the spray head is moved to position X/Y and, for
the [Spray time [s]] time, a spot is sprayed.
ð If no value is entered here, the spray head is approached to position X/Y.
During the travel movement, a path is sprayed with the [Spray amount
[%]].
ð The process has now been completed.

– Set number 1: Position [X = 13.5] / [Y = 29.5] is approached with [Nozzle 1] at a
speed of [130 mm/s]. The nozzle sprays a spot with a [30%] dosage for the
time of [0.5 s].
– Set number 2: Position [X = 25.3] / [Y = 29.8] is approached with [Nozzle 2] at a
speed of [130 mm/s]. The nozzle sprays a spot with a [30%] dosage for the
time of [0.5 s].
– Set number 4: This data set is hidden (the [Hide] checkbox is enabled). The
data set is therefore not processed.
– Set number 7: Position [X = 104.5] / [Y = 54.2] is approached with [Nozzle 1] at
a speed of [130 mm/s]. The nozzle remains there without spraying.
– Set number 8: The position [X = 104.6] / [Y = 65.9] is approached with [Nozzle
1] at a speed of [15 mm/s]; in the process, it sprays a path with a [30%] dosage.
This behaviour only occurs when the [Fluxer coordinates relate to nozzle 1] check-
box has not been enabled in the [Soldering program editor Set data] dialog.
