ROTHENBERGER ROWELD ROFUSE Plus V2.0 - Manual (Page 19)

ENGLISH 17
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. 7.2). 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.
5.4 Starting the Welding Process
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.
5.5 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.
5.6 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.
5.7 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.
5.8 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.
5.9 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.
5.10 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. 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 5).
To call the ViewWeld abstract of a welding report, press the ñ key in
the bar code input screen (see Display 2).
