It is under the user's responsibility to rely on the AutoWeld feature only when the preceding
and the planned welding 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, the input of all traceability data that were
enabled in the configuration menu (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 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 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 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 welding 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 unit or pressing the STOP/
RESET key will reset the unit back to the start of entering the welding parameters.
5.12
Using ViewWeld to Manage Logged Welding Reports, Print Tags,
and Assign Geo-data
The ViewWeld feature offers viewing
welding reports recorded during the welding processes and printing
it as a label tag to be affixed to the joint on the optionally available
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 6) where the first displayed abstract is that of the last
performed welding operation.
To call the ViewWeld abstract of a welding report, press the ñ key in the bar code input screen
(see Display 2). Browsing through the saved welding reports is then possible by pressing the ï or
ð cursor keys. To print a tag of the welding operation of which the abstract is currently displayed,
the label tag printer has to be connected to the welder. Then press the START/SET key in the
ViewWeld screen.
ViewWeld also enables assigning the geo-data of a joint after it was made, in case they were not
recorded with enabled geo-data logging at the welding operation (see Sect. 6.7). To do this, call
