COOLING (the fusion joint)
The cooling time in the base machine under fusion pressure must always
be observed. The use of cooling agents is not permitted during cooling.
During the cooling time the fusion pressure has to be supervised by the
operator and if necessary readjusted!
RELEASING (the hydraulic system)
Danger of bruising!
Release the pressure of the hydraulic system before opening the clamping stations.
Move control lever towards "open <>" (lever position: halfway between neutral and
fully open) until pressure on manometer shows nearly 0.
Do not open machine slides.
Open clamping station before removing welded pipes/fittings.
All fusion joints must have cooled completely before the pressure test is
performed. This is generally the case approx. 1 hour after the last fusion
operation.

Visual check of welding bead
Immediately after removing the welded pipes/fittings visually check the part for correct
cultivated double bead and the k-value.
