PRO-TIG AC/DC – next generation TIG welding system.
350 Amperes at 100% duty cycle – liquid-cooling integrated.
The PRO-TIG AC/DC combined premium welding
equipment technology with best-in-class
user-friendliness. The unique combination
of the Dual-Power inverter with the precise,
digital welding process control offers perfect
welding properties. Includes integrated torch
liquid cooling as a factory standard.
100% duty cycle for all devices
Maximum user-friendliness thanks to easy and
safe handling
XXClear-cut self-explanatory handling: easy and
fast operation of the PRO-TIG is no problem,
even when wearing gloves!
Perfectly stable arc
XXFast and precise welding process control: the
arc is kept stable in any position. Innovative
ignition management guarantees reliable
ignition.
High frequency pulse up to 3000 Hz
XXHigh-frequency pulse operation in a
frequency range above 2000 Hz ensures
a precise, focused arc with a high output
density. This ensures reliable and uniform
penetration while at the same time reducing
the heat impact zone. The higher arc
pressure naturally supports faster welding
speeds. The virtually unavoidable gap
fluctuations between the torch and the weld
pool in manual welding thus have virtually no
influence on the welding results.
Intelligent ignition management
XXThanks to advanced processor control, the
optimum ignition energy setting is chosen as
a function of the selected welding current for
both HF and Lift-Arc ignition. This quickly and
easily produces a stable arc - independently
of the tungsten electrode you are using - and
is gentle on both the workpiece and the
electrode.
TIG AC welding
XXThe AC arc remains smooth and stable even
with critical and highly oxidised material
surfaces. The quiet and appealing arc noise,
is well below the legally required limit.
Dual Wave Aluminium welding method
XXThis custom mode is a combination of AC
and DC welding. While welding the processor
control automatically switches between
0.2 seconds of DC and then 0.3 seconds of
AC welding current. The selected values for
welding current I1 or I2, the frequency and
balance are taken into consideration, just
like in DC- or AC-only welding. The Dual-Wave
method means improved manageability
of the weld pool and is used for welding
difficult workpieces (out-of-position
welding), when welding workpieces of
different thicknesses and when processing
thin sheet aluminium and aluminium alloys.
AC Balance control
XXAC Balance control controls the heat in the
tungsten electrode. The arc can be focused
based on the heat input, e.g., in welding thin
sheets or for welded-on edges. Reducing
the heat input also reduces the wear on the
electrode.
Automatic frequency control
XXThe frequency is automatically adapted to
match the current level in AC welding. The
AC arc is focused at low welding currents.
This ensures reliable root coverage, e.g.,
for fillet welds on thin sheets. The wear on
the tungsten electrode is reduced at higher
currents. The results are a long service
life, and best-in-class economic efficiency.
Automatic frequency control offers benefits,
especially if you work with a remote control
foot pedal. Additionally, the AC frequency
can be manually configured in the range of
30 - 300 Hz.
Generator capability
XXMore flexibility in mobile applications
ELSA.PRO system
XXThe proven ELSA (Electronic Stabilized Arc)
technology was enhanced for PRO-TIG. this
highly dynamic digital welding process,
with its unique precision and precise
reproducibility, ensures excellent welding
properties even for melt pools with large
surfaces.
Electrode welding
XXThe PRO-TIG is also a full-fledged electrode
welding device. In addition to the welding
current, hot start and arc force are freely
configurable. The electrode polarity is
selectable on the device (no need to unplug
and plug the welding and workpiece cables).
Of course, the PRO-TIG has the tried and
trusted anti-stick function which prevents
the stick electrode sticking and burning out.
Optimised energy efficiency
XXThe Dual-Power inverter has a uniquely
effective mode of operation. Thanks
to intelligent energy management, in
combination with the use of innovative
components, almost all of the supplied
power is converted into an arc. As energy
costs continue to rise, the PRO-TIG also
contributes to your economic success in
terms of energy consumption.

Plug&Play
XXPRO-TIG works with a smart CAN networked
multiprocessor architecture. All components
are automatically detected and configured by
the PRO-TIG. For the user this means: Plug &
Play – just plug in and start!
Integrated torch liquid-cooling
XXTorch cooling with a cooling performance of
1500 W it is also activated by plug and play.
Percent of fugal pump is requirements-driven
(Auto/On/Off). Once the torch's schooling is
sufficient, the liquid cooling system switches
to standby (torch temperature monitoring).
This reduces energy consumption and noise
emission. A flow monitor is also integrated.
