6 Entering Welding Parameters Manually (only ROFUSE+ V2)
To be able to enter the welding parameters manually, you have

first
to connect the fitting to the welding unit with the welding cable.
The manual input of the parameters can then be accessed by
pressing the ò arrow key. The screen will show a menu as
reproduced in Display 6 provided manual input is enabled in the
configuration menu (see Sect. 8.1). In other words, the manual
parameter input replaces reading the bar code of the fitting with a
scanner.
Using the arrow keys ñ and ò you can select “Enter Voltage/Time” or “Enter Fitting Code”
(i.e., the numbers that represents the code of the fitting to be used). Confirm your selection by
pressing the START/SET key.
6.1 Manually Entering Welding Voltage and Time
If this option was chosen in the manual parameter input menu,
Display 7
Voltage/Time

a
display like the one to the right appears on the screen. Use the
arrow keys п, р, с, т to set the welding voltage and the welding
time, according to the fitting manufacturer’s instructions, then press
the START/SET key to confirm your input. The “Start ?” message
displayed after the confirmation by START/SET indicates that the
unit is ready for welding.
6.2 Entering the String of Numbers
If this option was chosen in the manual parameter input menu, the “Enter Fitting Code” display
shows. The 24 characters of the fitting code to be entered display as asterisks ( * ). Use the
arrow keys п, р, с, т to enter the code and press START/SET to confirm your input and have it
decoded. If the code entered is not correct, an “Input Error” message appears; check the string
of numbers and correct as needed. If the code is correct, the decoded data is displayed, and the
“Start ?” message indicates that the unit is ready to start welding.
7 Dedicated Welding Unit Information
7.1 Displaying Characteristics of the Welding Unit
The key technical information on the welding unit itself is displayed by pressing the ð key at the
“Enter Fitting Code” screen. They are the software version, the serial number of the unit, and the
date of the next scheduled maintenance. To quit this screen, press the STOP/RESET key.
If the scheduled service is overdue, a service due message appears on the screen as soon as the
unit is plugged into the mains or generator power supply. This message has to be acknowledged
by pressing START/SET.
7.2 Measuring Resistance
When the START/SET key was pressed to initiate a welding process, the resistance value of the
fitting is measured and compared to the value entered as part of the read fitting code. If the gap
between the two values is smaller than the acceptable tolerance given in the code, the welding
process starts. If the gap is greater than the preset tolerance, the welding unit aborts welding
and displays a “Resistance Error” message. Furthermore, it displays the actual resistance value
measured for the connected fitting.
The reason for a resistance error may be poorly contacting and/or worn connection terminals.
Therefore, if this error occurs, check them for proper fit and, if worn, replace them with new
ones.
7.3 Overheating Switch
The welding process aborts if the temperature of the transformer in the welding unit is too high.
The overheating circuit breaker for the transformer stops the welding if the temperature reading
is too high and the remaining welding time is longer than 800 seconds. The display and the
welding report will show an “Overheated” message.
