How is it possible to limit current by the use of a variac? I mean, there is no air gap in the core or such things. Tried it several times in the past on my teslacoils to limit current with a normal variac and I never hat success with that.
Perhaps they modified the cores with an air gap..That's a pretty standard thing, discussed in the list archives, along with techniques, warnings, etc.
