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
pressure is linearly raised to the appropriate joining pressure.
