Cooling time

The system starts to build up the fusion pressure within the required time
according to the selected welding standard (t4): an uniform double
bead will be formed around the entire pipe circumference.
As soon as the fusion pressure is reached, the counter for the cooling
time t5 starts.
When cooling time is elapsed the system moves automatically to the
next step.
If the selected welding standard contains two cooling phases, the
controller switches automatically from cooling time 5 to 6.
The power to the heater plate could be switched off by means of the
toggle switch at bottom of the screen: this function is recommended for
the last welding of a day or a long break until the next one.
Attention
If pressure build up time t4 goes out of the tolerance range, the message
"ERROR OCCURRED!" is shown. The relevant error code will be
displayed at the end of the fusion process (see chapter 8.3.5) and an
error message will be also printed in the welding report (see chapters
10.2.3/12).
If pressure P5 goes out of the tolerance range, the message "ERROR
Attention
OCCURRED!" is shown and the symbol * appears close to relevant
parameter. The relevant error code will be displayed at the end of the
fusion process (see chapter 8.3.5) and an error message will be also
printed in the welding report (see chapters 10.2.3/12).
