Push Pull Preparation (Hardware)

With factory fitted or retro-fitted Push Pull
i i
preparation (hardware)
– If just the value 1 (analogue PushPull) is avail-
able in the machine configuration menu un-
der the parameter "PPn" (PushPull torch)
– you need to establish and set two parame-
ter values for the connected Push Pull torch
Setting Analogue Push Pull Torch
 Push the wire indeed button and check the wire feed di-
rection of the unit and the Push Pull torch. Both feeds must
transport in the same direction.
 If necessary, change the wire feed direction of the Push
Pull torch in the Machine Configuration menu under the
Parameter Code "PPd".
 Set the wire feed speed of the Push Pull torch in the Ma-
chine Configuration menu under the Parameter Code
"PPc".
Here the following applies:
– Low value = low speed
– High value = high speed
02.20
– If there is slip in the wire feed on the Push Pull torch,
or if the wire abrasion is too great, the speed of the
Push Pull torch must be reduced
– If the wire builds up between the feeds, the speed of
the Push Pull torch must be increased

Push Pull Upgrade

With the additional Push Pull Upgrade
i i
 If not already fitted, install the Push Pull Upgrade.
See Chapter "12 NFC Functions" on Page 28.
The unit must then be restarted (switching off/
i i
Selecting the Push Pull torch
 Select your connected Push Pull torch under the param-
eter "PPn" (PushPull torch) in the Machine Configuration
menu based on the "MicorMIG push-pull torch" list.
See Chapter "7 Menu Machine Configuration" on Page 24.
‰ If you select a supported Push Pull torch (2...31), no further
settings are required.
‰ If the Push Pull torch you are using is not present, use the
torch analogue Push Pull (1).
See Chapter "Setting Analogue Push Pull Torch" on Page 27.

Push Pull potentiometer torch

i i
The potentiometer is used to regulate the main parameter
wire feed speed. In the welding process Synergic and Speed-
Arc the display can be selected to show the main parameters
welding current and material thickness.
9 The current value, limited by the potentiometer, is dis-
played in the left-hand 7-segment display A4.
 Rotate the rotary button A41 by one position (one stop).
9 The maximum settable value on the potentiometer, is dis-
played for 2 secs.in the left-hand 7-segment display A4.
 Turn the rotary button A41 further within this 2 sec. period.
9 The maximum settable value is displayed and changed in
the left-hand 7-segment display A4.
‰ The minimum setting value on the potentiometer is lim-
ited in the welding process Synergic and SpeedArc of the
welding programme or in the manual welding programme
by the minimum unit setting.
‰ Under a limited authorization level (e. g. WPS Welder), the
minimum and maximum settable value depends on the
value of the prescribed parameter limits.

– If all supported Push Pull torches are avail-
able in the Machine Configuration menu
under the parameter "PPn" (PushPull torch)
– the wire feeds of the selected Push Pull
torch and the unit are synchronised
on).
Make sure that the potentiometer on the
torch is not set to minimum when the unit is
switched on. Otherwise the potentiometer
will not be recognised by the unit and remains
without function.
