"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.

5.6 Welding Process

The welding process is monitored for its entire duration
applying the welding parameters contained in the fitting
code. Along with the actual (left) and nominal (right) weld-
ing time, the welding voltage, the resistance, and the weld-
ing current are displayed in the lower line of the screen.

5.7 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.

5.8 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.

5.9 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 ac-
knowledged 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.

5.10 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.
