WARNING!
Operating the equipment incorrectly can cause serious injury and damage.
Do not use the functions described here until you have read and completely understood
all of the following documents:
These “Operating Instructions”
▶
All “Operating Instructions” for the system components, especially the “Safety rules”
▶
The digital series of machines stands out for the superb welding properties and unprecedented weld-process precision which their digital technology makes possible. Their
microprocessor-controlled inverter power sources permit exact reproducibility of welding
results.
For welding pipelines, the TimeTwin Digital welding system is used in conjunction with an
automated welding process. In this process, welding on the pipeline is performed by up
to four twin torches at the same time.
The system components of the Pipe series have been specially designed for use in
pipeline-construction under extreme climatic conditions. Their ability to withstand operating temperatures ranging from minus 50°C to plus 40°C means that they can be used
anywhere from Alaska to the Sahara.

the coolant
CAUTION!
Danger from using non-permitted coolant.
This can result in serious damage to property.
Only use coolant available from the manufacturer.
▶
Do not mix different coolants.

FK 9000 R Pipe
General remarks The FK 9000 R Pipe cooling unit is a cooling unit which has been specially designed for
use under extreme climatic conditions.
NOTE!
For information on how the Pipe version of the cooling unit functions, and how to
operate it, please refer to the “Operating Instructions” manual for the standard
cooling unit, as supplied with the Pipe version.
In cases where the properties or functions of the Pipe series differ from the standard
cooling unit, the data given in the document you are now reading will apply.
CAUTION!
Only fill or top up the reservoir of the FK 9000 R Pipe cooling unit with original
Fronius Pipe coolant (Art.
n° 40,0009,0079). Due to their electrical conductivity and inadequate material compatibility, and to the high thermal stresses encountered in this application, all other antifreeze
agents are unsuitable for use here.
