If the code entered is correct, it is saved to system memory and inserted into the welding reports
to be printed.
Only an ISO standard-compliant welder identification code is accepted by the unit. If the welder
code feature is disabled, the input screen for the welder code will not show.

contact. Use terminal adapters if needed. The contact
surfaces of the cable connection terminals or adapters and the
fitting have to be clean. Dirty terminals may lead to improper
welding and also to overheated and fused connection terminals.
Protect the cable connectors against getting dirty at all times.
Terminals and push-on adapters should be considered consumables
and, therefore, have to be checked before every welding operation
and replaced if damaged or dirty.
When the fitting is connected, instead of the “No Contact” message (see Display 2) the number
of the next welding report appears, e.g., “Prot. No.: 0015.”.
5.4
Reading the Fitting Code with a Handheld Scanner
Only the bar code on the tag sticking on the fitting to be welded may be used. It is not acceptable
to read the fitting code tag of a fitting of a different kind if the intended one is damaged or
unreadable.
Read the fitting code by holding the scanner in front of the bar

at a distance of 5 to 10 cm (2 to 4 inches), where the red line
indicates the reading area. Then push the reading button. If the
data are correctly read, the welding unit confirms this by an audible
signal and displays the decoded data on the screen (see Display 4).
The displayed values are the nominal welding parameters contained in the fitting
bar code. They are displayed before the actual resistance of the electrofusion fitting
is measured. This means that even when the showing ohm value is o.k., a resistance
error may still be detected (see Sect. 9.2). Only when the welding process starts, the
display shows the actual, measured welding parameters.
The “Start ?” message means that the unit is ready to start the welding process. Check the read
data and if you see that they are erroneous, delete them by pressing the STOP/RESET key. The
read data are also deleted if the welding unit is disconnected from the fitting.
5.5
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.
5.6
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.
5.7
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.
5.8
Aborted Welding Process
The welding process has failed if a plain-text error is displayed on the screen and the audible
signal is in the interval. An error has to be acknowledged by pressing the STOP/RESET key.
