General
Principle The FPA 3020 is a completely digitised, microprocessor-controlled inverter power source
for orbital welding. An active power source manager is coupled with a digital signal
processor, and together they control and regulate the entire welding process. The actual
data are measured continuously, and the device responds immediately to any changes.
Power source FPA 3020
Device concept
Typical of the new power source is its adaptability to the many demands of orbital
welding. The cooling unit, tted as standard, makes a signicant contribution. In ad-
dition to the many orbital welding guns available for the most varied applications, the
power source also supports manual welding torches. Further convenience is added by a
remo- te control unit that has all the necessary functions for operating the orbital welding
system on site.
Application areas There are a vast number of applications for the FPA 3020 in trade and industry. At this
point the pharmaceutical and foodstuffs industries are well worth mentioning, since they
place high demands on the quality of pipelines and containers. As regards suitability for
welding different materials, the power source is just as suitable for welding unalloyed and
low-alloy steel as it is for welding high-alloy, chrome-nickel steels. These „all-roun- der“
qualities are enhanced by the optimised ignition sequence of the device.
For TIG-AC welding, the FPA 3020 takes account not only of the diameter of the
electro- de, but also of its temperature, calculated with reference to the preceding weld-
ing and weld-off times. Moreover, the power source does sterling service when welding
alumini- um, aluminium alloys, copper alloys, magnesium and titanium. The AC fre-
quency can be adjusted over a very wide range, permitting optimum adaptation to your
particular re- quirements.
The control algorithms ensure that the
specied target status is maintained at
all times. This gives the weld process an
unrivalled degree of precision, with exact
reproducibility of all results and excellent
welding properties. Alongside the welding
properties, the high degree of efciency
is another key feature of the new orbital
power source.
An intuitive operating concept makes your
work much easier. Last but not least, as
the tasks of the related control elements
are now controlled from the generously
proportioned touchscreen, essential func-
tions can be seen at a glance and adjusted
as required.
