Speed alignment
for hot-wire
applications
Important! With hot-wire applications, the wirespeed must be exactly fine-tuned to the
1 to 5 m/min range. With standard applications, the 1 to 22 m/min range should be used
(see previous section: "Checking the motor speed on the Robacta Drive").
To carry out a speed alignment to a wirespeed of 1 to 5 m/min, proceed as follows:
-

Fig.6
Note! Only carry out the alignment on a completely tooled-up system (the
wirefeeder and Robacta Drive must have been mounted at the robot). Where an
installation is supplied under an "FMP" order (the German initials stand for
"ready mounted and test-welded"), the speed alignment must be repeated in-
situ, due to the different conditions encountered here.
Couple the whole system together (complete with welding wire!)
Caution! Risk of injury from welding wire emerging at speed from the torch.
Hold the torch so that it points away from your face and body.
Check the direction of rotation
Specify a wirespeed of 1m/min (command value from robot)
Measure the length of wire that has been fed after 1 minute (must be 1 m).
Note! The speed of the Robacta Drive is controlled with reference to actual
values and so must also correspond with the pre-set value.
P.-c. board PZ45RO
Correction possible with P2 on p.-c. board
PZ45RZO:
- Specify a wirespeed of 5m/min
(command value from robot)
- Measure the length of wire that has
been fed after 30 seconds (must be
2.5 m)

Drive is controlled with reference
to actual values and so must also
correspond with the pre-set value.
