These power sources have been built using the latest inverter technology

Continuous current adjustment from minimum to maximum makes it
possible to ensure a high quality cut over changing metal thickness and
type.
The cutting cycle is activated by a pilot arc that, depending on the model:
can be struck by shorting between electrode and nozzle or by a high
frequency discharge (HF).
