1 bar on manometer: 348 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 !
