GENERAL REMARKS
Individualized systems for every application
Fronius offers system solutions. Long-lived and highly
cost-effective welding systems are just as much a
part of this as are individually customized planning,
advice, corrective maintenance and servicing. The aim
is perfect welding results and a high level of customer
satisfaction. The MIG/MAG robot torches from Fronius
make a major contribution here. They are available in
both gas-cooled and water-cooled versions, and – as
needed – either with or without Robacta Drive, the
extra master drive on the 6th axis of the robot.
Many different lengths of hosepack are possible,
as are special, customized torch-body geometries.
For welding-tasks anywhere between 170 A and
700 A. It goes without saying that the individual
system components are all designed for optimum
interoperability and specifically tailored to the type
of robot concerned. Whatever your welding application,
with Fronius you will always find a whole world of
solutions.
The whole wide world of robot welding torches
ECONOMY
Cost-savings and long endurance times
When it comes to economy, the list of criteria fulfilled
by Fronius welding torches is a long one. It begins with
their high-grade wearing parts and spares, which are
responsible for a high level of system availability, and so
it finishes with measurable savings – on gas costs, for
instance.
Precision, robust contact tubes
The contact tube plays a key role in welding torches.
A Fronius contact tube is made of high-grade copper
alloy, ensuring a long service life. What is more,
measuring 10 x 40 mm (0.39” x 1.57”), it is very
generously sized, and so can dissipate the heat very
effectively, and ensures stable contacting. Other
features of Fronius contact tubes include the precision
tailoring of the diameter to the wire, and the centricity of
the bore.
Loss-free gas feed all the way from the cylinder to the nozzle
On the gas-cooled torches, considerable savings are
possible just from the gas feed arrangements. The gas
is routed down a single hose, in one uninterrupted duct,
all the way from the gas cylinder to where it flows out
of the torch. This prevents any gas leakage and saves
up to 10 % of the gas costs. There is also a separate
duct for the gas in the torch body itself – so gas cannot
escape to the rear either.
The electromagnetic cleaning system Robacta TC Cool cleans
welding spatter from the gas nozzle without touching it. The cleaning
results are consistently good, and the service life of the gas nozzle is
prolonged.
The 10 x 40 mm (0.39” x 1.57”)
Fronius contact tube dissipates the
heat very effectively and ensures
stable contacting. Its service life
is enhanced by the high-grade
materials and precision methods
used in its manufacture.
Wearing parts that stay cool live longer
The better the torch body is cooled, the cooler the
wearing parts will remain and the longer their
endurance times will be. The Robacta welding torches
make an excellent job of this. Also, the gas nozzle and
contact tube are much easier to clean when less spatter
clings to them – and the cooler these wearing parts can
be kept, the less spatter adheres.
Being touchless, the Robacta TC Cool cleaning system
provides a particularly gentle method of cleaning. The
spatter is removed electromagnetically, meaning that
no damage is done to the surfaces of the wearing parts.
Robacta TC touchlessly cleans the torch in automated
steel applications. The surfaces of the wearing parts
are not damaged, and the lifespan of the gas nozzle is
prolonged – with consistently defined cleaning results
every time.

WELDING PROPERTIES
Meets all the requirements for an ideal weld process
The quality of the welding torch has a critical influence
on the weld process as a whole, and thus directly on
the welding quality. So when it comes to your torches,
why put up with anything less than the best?
What are the key factors making for a perfect welding
process? Prime among them are the contacting, the
wire guidance and wire travel, the gas-shielding, cooling
and ignition, the welding operator and the flexibility of
the hosepack. And Robacta takes the best possible
care of all of these.
Contact guaranteed
On water-cooled welding torches, the forced wire contact makes sure that the welding wire is guided into the contact tube at an exactly defined angle. Dependable current transfer is the result, even when using bulk pay-off packs where the curvature of the wire would otherwise impair the wire guidance. Another positive result of the forced wire contact, incidentally, is a boost of up to 100 % in the contact-tube endurance time.
Why not go for something better?

Metal transfer
Spatter-free ignition
The forced wire contact ensures dependable current transfer.
The weld process becomes more precise, and there is less
wear-and-tear on the contact tube.
Wire travel with no margin of error
When it comes to wire travel, the water-cooled Robacta
models have any number of features to make sure that
the wire gets to where it is needed without the slightest
margin of error. Like the digital actual-value pick-up,
which causes exactly as much wire to be available as
the system requires at any given moment. The result is
spatter-free ignition and high-quality weld-seams.
Another feature is the drive rollers, which are
intermeshed so that the force is transferred to both
rollers simultaneously. Their diameter of 23 mm (0.91”)
makes them as much as 50 % larger than conventional
feed rollers. This guarantees optimum force
transmission at all times, with less risk of slippage.
What is more, the rollers provide 4-point contact
support for the wire as this is run through a specially
shaped groove. This brings a – measured –
30 % improvement in force transmission.
More drive for soft wires and long hosepacks
In addition to the wirefeeder, with Robacta Drive there
is also a powerful, highly dynamic DC servo motor
mounted on the 6th axis of the robot. As well as
providing perfect ignition properties (SFI), this master
drive also reliably stabilizes the entire welding process.
No matter whether you are using small hosepack radii
or soft wires such as aluminum or copper-silicon, the
push/pull operation is an equally effective guarantee of
precision wirefeed in either case. Superior quality, after
all, is something that results from the interplay of many
different factors.
Robacta Drive has an extra
wire-drive. This ensures
precision wirefeed even when
using soft wires and long
hosepacks.
Uniform force transmission from intermeshed drive rollers.
23 mm(0.91") The wire is held at 4 contact points in the drive rollers,
and so is fed reliably and without slippage.
HANDLING
Quick and uncomplicated
In automated applications, every second counts.
Whenever a wearing part needs to be changed any-
where, this has to be done quickly. The quicker, the
better, in fact. And with Robacta, everything has been
developed and tested to be quicker still.
On Robacta Drive, on both the gas- and water-cooled
variants, fast, troublefree wireguide changes are not
just mandatory – they’re guaranteed: press, pull, insert
– that’s it. For the first time in welding history, this
makes it possible to change the inner liner without long
downtimes. In the space of just a few seconds, in fact.
On the gas-cooled welding torches, the big issue is all
about changing the gas nozzle. And with QuickSnap,
this is now a split-second job. It’s much faster than
screwing the gas nozzle on and off, and fixes it on just
as reliably – with a mechanical locking mechanism. The
other advantage of this is that the gas nozzle always
stays in the same position.
When the time comes to change the torch body, this
also needs to be done very quickly. For this reason,
the torch body is clip-fitted, and is easy to lock. It is
manufactured with such precision that after it has been
changed, the TCP remains unchanged, to within a range
of +/- 0.2 mm (0.008”). In addition, the Robacta testing
device is used to check Robacta torch bodies for any
dimensional discrepancies. Precision re-adjustment of
the torch bodies is thus possible in a very uncomplica-
ted way.

This prevents unnecessarily long downtimes.

SYSTEM
A first-rate system for every power level and every application
Fronius offers ingenious system solutions for
all power classes and robot applications. The
spectrum ranges from gas- and water-cooled
welding torches to push/pull-systems, and even
to hosepacks integrated in the robot arm.
Hosepack either on the outside or integrated in the robot arm
Fronius offers the ideal system solution for
welding-robots with integrated media guidance.
The hosepack runs directly inside the process arm
of the robot. Here, it is kept safe and protected,
also providing better accessibility in all welding
positions. Otherwise, the hosepack can be routed
on the outside, parallel to the robot arm.
Systematic wire guidance for every material
On Robacta, the wirefeeder is mounted on the
3rd axis of the robot. The wire is constantly and
accurately pushed forward. For very soft wire
electrodes, Fronius has developed a second
wirefeeder: Robacta Drive. This is mounted
directly on the frontmost axis of the welding robot
as an additional master drive, and is integrated in
the torch. It ensures absolutely uniform wire travel,
making for the very greatest precision in
the welding process.
Gas- and water-cooled systems
Fronius offers gas- and water-cooled robot-
welding torches. Water-cooled welding torches
are given optimum cooling. This prolongs the
service life of the wearing parts, making this a
highly economical solution. A big “plus” of
gas-cooled welding systems is that they need
less maintenance. They also make applications
at below 250 A economically feasible. The choice
between gas- or water-cooled will also depend
on other factors such as the stick-out length,
pulsed-arc mode or the type of shielding gas.
