1 bar on manometer: 232 N
PE 80 The value for heating element temperature is between 200 ° C - 220 °C (392 °F - 428 °F).
The smaller the pipe wall the higher the temperature.
PE 100 The standard value for heating element temperature is 220 °C (428 °F).
Increase the change-over time and the welding pressure time at PE 100 as fast as possible !

Remaining under the cool-down time for up to 50% is allowed under the following conditions:
•
prefabrication under workshop conditions
•
low additional pressure at unclamping
•
no additional pressure during further cooling down
•
load onto the workpieces only after being completely cooled down
•
Join parts with wall thickness ≥15 mm
