The Active Wave

Fronius digital TIG systems use a digital signal processor, and offer all the benefits already familiar fromother digital welding systems: Reproducibility, precision and promptness. Along with complete digitization, we added something quite special: Silence. Noise – caused by the constant changing of the welding current from positive to negative – was always an issue with TIG AC welding. Now silence rules with Fronius Tig.

Fronius calls the underlying principle Active Wave, because the digital signal processor always calculates precisely and in real time the current curve that offers the highest possible arc stability and lowest possible noise emissions. Neither is there any more high-frequency superimposition with alternating current.

Moreover, all TIG systems have now been completely digitized , i.e. all components that belong to a perfect welding process.

The perfect wave, so to speak.


Resonant Intelligence

Our electrode inverters belong to the family of digital welding systems, but also have added intelligence. Or more precisely, resonant intelligence. What does this mean? Using resonant intelligence, the arc directly influences the output.

The advantage: resonant intelligence reacts to every minute change in the arc. The result is always a perfect and constant arc, and the best welding results. Added to that are adequate power reserves and an ideal characteristic.

A further problem with single-phase machines is also solved using resonant intelligence: welding with long input power cables. Sufficient power reserves mean that cables 100 feet in length (for example) can be used without any loss of power. For example: 1/8 " cellulose electrodes that previously could not be used with single-phase systems are now easy to weld. Absolutely problem-free, even in vertical down seam position.

In a word, resonant intelligence always works, and produces the best results.
