The standard value for heating element temperature is 210 °C ± 10 °C / 410 °F ± 50 °F.
The
smaller
the pipe wall the
higher
the temperature.
Additional to the given bead-up force and to the welding force the moving force of the support must be added !

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
