Calculating of the fusion pressure

The fusion pressure is the sum of the "table value + movement pressure"

Adjusting of the fusion pressure

15. Open completely the machine.
16. Reduce pressure with the fine-adjustment pressure valve (turn counter-clockwise).
17. Move control lever towards "close ><" position and increase the pressure on the
pressure valve (turn clockwise) until clamping carriage moves smoothly.
18. Adjust fusion pressure with the fine adjustment pressure valve as soon as both pipe
ends are in contact (turn clockwise, keep control lever in position close).
If the fusion pressure is set too high, re-adjust:
1. Open completely the machine.
2. Turn the fine-adjustment pressure valve approx. 3 revolutions counter clockwise.
3. Start fusion pressure adjustment again.
