The Digital Revolution

To see the benefits of the digital revolution in welding technology, let’s try listening first: to some music. Why? Simple: Not so very long ago, the good old vinyl record was the most important medium. The only problem was that it soon reached its limits in terms of quality. The more frequently it was played, the more the sound quality deteriorated.

With digital technology, music remains music no matter how often a song is played. The quality remains the same.

The same applies to Fronius digital welding technology: 100 % reproducible welding results. Again and again. As often as you want. The basis for this is the highest possible precision in the welding process. And it’s completely digitally controlled.

The principle of full-digital control of the welding process

When welding, certain values (command values) are desirable, e.g. with regards to current or voltage. And then there are the actual values. These are digitised and constantly compared. If there are any discrepancies, they are adapted to comply with the command values. The digital signal processor is what makes this possible. A powerful microcontroller that processes all the data with maximum precision. The result: an absolutely perfect arc. And that in turn means perfect ignition, welding and unique reproducibility of weld seams.

In conventional welding systems, the constant adaptation from actual to command value is carried out using analog components. They are not as precise, which results in, shall we say, “problems” with long term stability.

This is precisely where the advantage of digital technology comes to the fore. With completely digitally controlled systems from Fronius, all the power is in the software, in the embedded expert knowledge. The system is therefore flexible and also open to future developments. With regard to the system, we haven’t of course just fully digitised the power source: all our welding components are now digital. Because we know that to enjoy the harmony, the whole orchestra has to be in tune. All the time. This closes the cycle.
