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>.

Heating element temperature and actual pressure
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.
