General

Device concept

The TIG pulsed arc function, with its wide frequency range, is available on both the Mag-
icWave and TransTig.
To optimise the ignition sequence in TIG AC welding, the MagicWave takes account not
only of the diameter of the electrode, but also of its temperature, calculated with reference
to the preceding welding and welding off-times.
Functional princi- The central control and regulation unit of the power sources is coupled with a digital signal
ple processor. The central control and regulation unit and signal processor control the entire
welding process.
During the welding process, the actual data is measured continuously and the device re-
sponds immediately to any changes. Control algorithms ensure that the desired target
state is maintained.
This results in:

Application areas

The devices are used in workshops and industry for manual TIG applications with unal-
loyed and low-alloy steel and high-alloy chrome-nickel steels.
The MagicWave power sources perform exceptionally well when it comes to welding alu-
minium, aluminium alloys and magnesium due to the variable AC frequency.
a precise welding process,
exact reproducibility of all results
excellent weld properties.
The TransTig (TT) 230i, MagicWave (MW)
190 and MagicWave (MW) 230i TIG power
sources are fully digitised, microprocessor-
controlled inverter power sources.
Their modular design and potential for sys-
tem add-ons ensure a high degree of flexi-
bility. The devices can be adapted to any
situation.
The power sources are generator-compa-
tible. They are exceptionally sturdy in day-
to-day operation thanks to the protected
control elements and their powder-coated
housings.
