If the welding process is interrupted using EXIT the message "Termination by the operator" ap-
pears, the pressure is dissipated and the welding parameters are stored. Confirm the message
with OK, then the program jumps to the main menu.
 Release the pressure using the Automatic button (1) as soon as the required bulge height
has been reached evenly around the whole circumference of both pipes. The warming up
time t1 begins to run.
 Set the pressure so that the ends of the work pieces can again be lain uniformly and nearly
pressure-free onto the heating element.
A signal sounds shortly before the end of the warm-up time.
 After the warm-up time is over, separate the work pieces, remove the heating element and
bring the work pieces back together.
 Stop the bringing together process by releasing the buttons shortly before the ends of the
workpieces make contact (about 1 cm.) and press the buttons again immediately. The pres-
sure is linearly raised to the appropriate joining pressure.
When joining pressure is reached, the program automatically goes to the joining process and the
t4 timer starts.
The upper progress bar shows whether the pressure lies within the
correct range (green) or within a permissible (yellow) tolerance range
or whether it lies outside (red) the tolerance range. The actual pres-
sure is shown on the display (2).
