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 operation and electrofusion
Important
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 AutoW-
eld feature was called, the input of all traceability
data that were enabled in the configuration menu
Info
(see Sect. 10.2), is requested by 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 mes-
sage "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 weld-
ing current are displayed in the lower line of the screen.
5.8 End of Welding
The welding process ends successfully if the actual weld-
ing time corresponds 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 dis-
played on the screen and the audible signal buzzes con-
tinuously. An error has to be acknowledged by pressing
the STOP/RESET key.
