same welding parameters succeed each other, it is not necessary to
read a fitting bar code or enter welding parameters manually. To start
a welding operation that is fully identical to the preceding one, it is
sufficient to use the AutoWeld feature, provided it was enabled in the
configuration menu (see Sect. 10.1). It is accessible from thre quick
selection screen opened from the "Enter Fitting Code" screen with
the ï arrow key (see Sect. 6.1). In this screen, the selection cursor can
be moved using the ñ and ò; the selection is made with the START/
SET key.
It is under the user's responsibility to rely on the AutoWeld
feature only when the preceding and the planned welding
Important
operation and electrofusion fitting are really fully identical
to each other. An erroneous or negligent use of the feature
will result in a poor, unstable joint.
5.6 Starting the Welding Process
After the fitting bar code was read or the AutoWeld feature
was called, the input of all traceability data that were enabled
in the configuration menu (see Sect. 10.2), is requested by
Info the system.
After reading or entering the fitting code, the welding process can
be started using the START/SET key, when the "Start ?" message is
displayed and there is no indication of a problem.
Pressing the START/SET key will trigger a confirmation message "Pipe
treated?," which in turn requires a confirmation with the START/SET
key to start the welding proper.
5.7 Welding Process
The welding process is monitored for its entire duration applying
the welding parameters contained in the fitting code. The welding
voltage, the resistance, and the welding current are displayed in the
lower line of the screen.
5.8 End of Welding
The welding process ends successfully if the actual welding time cor-
responds to the nominal welding time and the buzzer can be heard
twice.
5.9 Aborted Welding Process
The welding process has failed if a plain-text error is displayed on the
screen and the audible signal buzzes continuously. An error has to be
acknowledged by pressing the STOP/RESET key.
5.10 Cooling Time
The cooling time as given in the fitting manufacturer's instructions has
to be respected. If the bar code provided by the fitting manufacturer
contains cooling time data, it will be displayed at the end of the weld-
ing process and will be counted down to zero. This countdown can
be acknowledged and canceled at any time by the STOP/RESET key.
However, note that for that time the pipe fitting joint which is still
warm must not be subjected to an external force. No cooling time is
displayed if the fitting code does not contain any such information.
5.11 Returning to the Start of Parameter Input
After welding is finished, disconnecting the welded fitting from the
