Some specific functions at some modern AC/DC machines are AC-pulse and so called "Hybrid AC-DC arc" as named at OTC or "MIX AC/DC" as named at Kemppi. At later, half od cycle is typical DC- current and other half is typical AC current. One may play with frequency, time of DC- versus time of AC, amperage of both (in general MIX AC/DC turns out to be alike AC pulse).
The reason why I used AC pulse or MIX is less fluid pool while control is set only on panel. Once we got pedal, the control of pool fluidity is perfect, so we forgot AC pulse and MIX.
But I read about Miller independent control of amperage of EN and EP current at AC welding. For example, one may set 100A of EN and 60 A of EP, combined with AC balance and AC frequency.
Anybody tried it? Any feedback? Or any opinion how useful it is or might be?
