Using ViewWeld to View Welding Reports and Print Tags

The ViewWeld feature offers viewing an abstracted version of the
welding report recorded during the last welding process and print-
ing it as a label tag to be affixed to the joint on the optionally avail-
able tag printer. The ViewWeld abstract shows the report number,
the date and time of the welding and the welding parameters along
with an evaluation of the quality of the joint/welding operation (see
Display 36).
To call the ViewWeld abstract of a welding report, press the ñ key in
the start screen (see Display 3). To print a tag of this operation, press
the START/SET key in the ViewWeld screen.
The ViewWeld abstract that shows on the screen depends on
the currently selected welding process. If the welding cable
Info

Heating element temperature will be increased automatically.
Heating element temperature will be reduced automatically.
It took too long to retract the heating plate and bring the pipes to
joining; welding will have to be repeated.
Impossible to determine the drag pressure; maybe pipes will have to
be clamped once again; or the pressure is below 1 bar, which is not
feasible for technical reasons.
Build-up pressure too high or too low and was not re-adjusted in
time.
Heating pressure too high and was not re-adjusted in time.
Joining pressure too high or too low and was not re-adjusted in
time.
Operator has stopped the cooling time by pressing the STOP/REST
key.
Heating element temperature is out of tolerance; impossible to
re-adjust the temperature; maybe the ambient temperature was too
low.
The input voltage is below 175 volts. If the error condition persists
for longer than 15 seconds, the welding process will be aborted. If
the voltage goes down below 170 volts, the welding process will
abort immediately.
The input voltage is over 290 volts. If the error condition persists for
longer than 15 seconds, the welding process will be aborted.
The resistance value of the connected fitting is out of the read
tolerance.
The frequency of the input voltage is out of tolerance
(42 Hz - 69 Hz)..
The message is displayed if the there is a momentary current failure
or if the current decreases by more than 15% per second for
3 seconds.
The output current value is in excess; possible causes: short-circuit in
the heater coil or the welding cable. During the start stage the
upper abort threshold equals 1.18 times the value at start, in any
other case the upper limit depends on the load value and is
calculated as the current at start plus 15%.
The dynamic current value during welding differs by more than 15%
from the required value, indicating a short-circuit in the heater coil.
