Some French guy had a moment of idiocy there I think.
Dc welding puts way less stress on tig torches and if it copes at 200 on ac it will breeze 200 on dc.
However, despite it been a pointless limitation it’s better this way than limiting the ac from a practical point of veiw.
I cannot remember the last time I used a tig on dc anywhere near 150amps. If I needed that sort of power I’d be plugging in the stinger. On ac however 160 amps is 3-4mm gage power on aluminium and I’m regularly up and beyond that. So the conclusion is as far as I’m concerned pointless yes but relatively harmless
