Fusion process

2.7.1
During the fusion process, the display shows the information
concerning the output voltage, the remaining fusion time and the
applied energy.
The machine adjusts the fusion time according to the external
Note
temperature and barcode information. Therefore the final fusion time
values might be slightly different from the nominal values, captured
from the barcode.
The fusion process can be stopped at any time by the operator
by pushing
immediately stops and an error message occurs (see 'Error
Messages' chapter).
Warning
Stopping the on-going fusion process will result in a suspicious
welding: the responsability will be in charge of the operator.
When the fusion operation is going to finish, a repeated acoustic
signal alerts the user that the process is near to complete. As soon
as the fusion process is correctly concluded, the display shows
briefly the information concerning the real fusion time, the average
voltage and the total energy applied to the jointing. These data will
be part of the welding protocol stored into the internal memory.
