increase. Watch the value on the display screen. Building
the joining pressure must correspond to a linearly increas-
ing ramp and its duration must neither be longer nor short-
er than indicated for your welding situation in the welding
value tables in the Appendix at t
4
.
Once the joining pressure is reached and has stabilized at
P
5
+ P
t
, the pressure will be kept at this level until the end of
the joining/cooling stage (t
5
in 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 mini
-
mum cool-on time (t
6
in the diagram). In most cases, how-
ever, t
6
is not relevant to the welder.
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.
4.5
Aborted Welding Process
If an error condition is detected, the machine aborts the
welding process and displays the error. However, this is only
possible when welding according to the Weld Control 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 malfunc-
tion starts flashing.
The errors listed in the following table can be displayed on
the screen.
Type of Error
Description
a. Data Input
Input Error
Error while entering data with the cursor keys.
Code Error
Error while reading data from a bar code or an RFID card.
b. System and Conditions
System Error
The welding system has to be disconnected immediately
from both the power supply and the basic machine chassis.
The auto-test has detected an error in the system. The
system must no longer be operated, but has to be checked
and possibly repaired. Contact the manufacturer.
Clock Error
The internal clock of the machine is defective; re-set the
clock in the configuration menu.
