If alignment of the pipes is correct, open the machine and confirm with button
<Enter>.
The mismatch may not exceed 10 % of the wall thickness.
In case of higher mismatch, readjust the pipe ends in the clamping devices and
repeat the planing process.
Abort the welding process by pressing button <C>.
5.7.6. Bead up
Insert the heating element into the basic machine. Move the pipes in the basic
machine onto each other.

Slowly increase pressure until actual pressure = desired pressure (when
desired pressure is reached, a beep sound can be heard).
Maintain pressure until the pipe end lays completely at the heating element and
a bead according to DVS has been formed.
