4.4.4 Joining and Cooling Stage

Set the carriage mover lever to its close-in position again in order to
move the pipe butts in on each other and to build the joining pres-
sure (P
+ P
) according to a consistent increase. Watch the value on
5
t
the display screen. Building the joining pressure must correspond to a
linearly increasing ramp and its duration must neither be longer nor
shorter than indicated for your welding situation in the welding value
tables in the Appendix at t
Once the joining pressure is reached and has stabilized at P
pressure will be kept at this level until the end of the joining phase (t
the diagram). In this stage, the new joint also starts cooling down.
Pipe and fitting manufacturers may include data on how long the new
joint should not be exposed to external strain. Also, the applicable
welding standard may require a minimum cool-on time (t
gram). In most cases, however, t

4.4.5 End of Welding

The welding is finished at the end of a successful joining and cooling
stage. The welder has to shut the pressure off from the pipes using
either the manual pressure release valve or the START/SET key.

Aborted Welding Process

If an error condition is detected, the machine aborts the welding pro-
cess and displays the error. However, this is only possible when welding
according to the WeldControl mode of the butt-welding process. In
the Manual Mode of butt welding, error detection is not available.
The error that made the welding abort is displayed on the screen (see
Display 32). Additionally, in the welding diagram the LED that belongs
to the welding stage with the malfunction starts flashing.
The errors listed in the following table can be displayed on the
screen.

Error while entering data with the cursor keys.
Error while reading data from a bar code or an RFID card.
The welding system has to be disconnected immediately from both
the power supply and the fitting. The auto-test has detected an
error in the system. The welder must no longer be operated and has
to be sent to an approved shop for check and repair.
The internal clock of the machine is defective; re-set the clock in the
Configuration Menu.
The recommended next service date for the welder is overdue. The
service due message has to be acknowledged by pressing the START/
SET key. Send the welding system to the manufacturer or an
approved service point for service and check-up.
The last welding is incomplete. The welding unit was disconnected
from the power supply voltage while it was in progress. To go on
using the unit, this error has to be acknowledged by pressing the
STOP/RESET key.
