TPS 320i

The TPS 320i, 320i C and 300i nc MIG/MAG power sources are completely digitised microprocessor-controlled inverter power sources. The modular design and potential for system add-ons ensure a high degree of flexibility. The devices can be adapted to any specific situation.

Functional principle:
The central control and regulation unit of the power sources is coupled with a digital signal processor. The central control and regulation unit and the signal processor control the entire welding process. During the welding process, the actual data is measured continuously and the device responds immediately to any changes. Control algorithms ensure that the desired target state is maintained.

This results

A precise welding process
Exact reproducibility of all results
Excellent weld properties.
