Reweld

Rewelding can be executed only after the welding process is aborted in the critical
section . It is the attempt to limit the ensuing damage and should prevent the
medium from leaking out the tubes . If rewelding is selected, the user is given the
possibility before welding to clamp the tubes and to choose the right type of tube in
the settings .
The user must check the quality of welding after a welding. The welding must be
repeated if needed. A risk assessment regarding the sterility of the weld has to
be perfomed by the user.
Make sure that the rewelding is not discontinued. If this occurs, no reweld is
possible anymore and the device has to be fixed by a technician.

After the reverse of the device due to an abort of the welding process in the
critical section, there is risk of weld failure and damage to the device. A risk
assessment regarding the sterility of the weld has to be perfomed by the user.
