Adjustments
6. 1. 1.
General
The following information concerns routine checks
and adjustments to be performed periodically or as
often as necessary.
These operations are not the same as calibrations that
have to be done periodically in order to satisfy quality
system requirements, according to ISO 9000 or Quali-
ty Assurance regulations. These calibrations must be
performed using inspection equipment which has itself
been calibrated in accordance with written procedures
by personnel appointed for that purpose. If speci
fi
cal-
ly requested, we can carry out these calibrations on
the customer’s site or in our workshops.
When to adjust?
Due to the ageing of components, a drift of the
source characteristics may occur gradually. There-
fore it is recommended to check the power source
adjustments once a year.
Exchange of cards or the source
Adjustments are required if card 0028029200 or the
“hot wire” current source and card 0028029400 or
the welding current source are replaced.
Servicing, maintenance and troubleshooting

Adjustment of the tachometer
6. 1. 2.
If the power source is equipped with the optional
tachometer card, it is recommended to check whether
the programmed speed corresponds to the real travel
speed achieved by the rotation of the welding head.
The adaptation kit for the welding head connections
must be installed correctly. In home position a sign
should be marked as point of reference on the
fi
x part
of the welding head..

"N+" again. The welding head
will now carry out a rotation of 360°. After the end
of the cycle, verify by means of the point of refer-
ence whether the rotation really stopped at 360°. If
the achieved result is correct, leave by pressing the
button
BT 2
(N- = QUIT).
If the result is not o.k. adjust the travel speed of the
welding head with the corresponding potentiometer
(to identify the potentiometer, refer to the appropri-
ate operating manual) and repeat the procedure until
the rotation stops correctly at the point of reference.
Verify the adjustment by carrying out a weld cycle in
simulation mode.
Using the GUI software (PC or touch screen)
Using the touchscreen, program a 360° rotation and start
a weld cycle in simulation mode. After the end of the
cycle, verify by means of the point of reference wheth-
er the rotation really stopped at 360°. If the achieved
result is correct the welding can be carried out.
If the result is not o.k. adjust the travel speed of the
welding head with the corresponding potentiometer
(to identify the potentiometer, refer to the appropri-
ate operating manual) and repeat the procedure until
the rotation stops correctly at the point of reference.
