The TIG orbital power sources control a certain number of axes by means of electronic cards, which can be more, or less sophisticated.
The importance of intelligent cards for TIG orbital power sources
The most complex electric circuit board can control nearly all kinds of motors. Thus, allowing the power source to know, at any given moment, the position of the electrode, as well as the direction of the rotation etc.
As previously mentioned, an axis is a motor that has to be controlled. Different types of motors are used in orbital welding: stepper motors, brushless motors, DC motors. As soon as an axe moves the power source keeps track of the rotations of the motor by means of a coder or a tachymeter.
At which moment does the intelligence of electronic cards makes a difference for the power source?
You can find various electronic boards that are able to control just one or two types of motors. AXXAIR only uses the most sophisticated electronic cards that can control any types of motor. This is an important advantage for the welder, as he can use any suppliers weld heads.
In practice, how can you define the compatibility between an orbital power source and the different welding heads?
Two different aspects must be considered :
- Firstly, the intelligence of the cards in order to control all the axes - and secondly, an adapter kit which permits the mechanical connexion between the welding head and the power source.
- The second point is the easiest one, as you only need the right connectors in order to plug the welding head, of any supplier, to the power source.
All suppliers of TIG orbital power sources, offer a range of adaptor kits. But if the electronic cards cannot control the right motor, you will have to buy – in addition to the adapter kit – a new circuit board that must be mounted in the power source.
Thanks to the sophisticated electronic cards used by AXXAIR, you gain flexibility as we can control – using our standard version – all orbital welding heads. This is a Substantial advantage as the welder can use a welding head from all the different manufacturers. We have demonstrated this directly at our customers’ facility by connecting the welding head of another supplier to show that it works.
