There's a guy in this video that lie high frequency. It's an interesting video if you haven't watched it.

Yep, it’s interesting how much Chris dispels the old myths about aluminum welding.

i think my previous explanation was a bit crap.
ac freq is probably better thought of like dc pulse but Ep is peak amps. and EP is background amps. unfortunately my cheap machines don't have individual en/ep adjustments or any fancy waveforms.
