At the very low end of its range, a Variac limits current just fine. I
worked as a calibration technician at Tektronix for years, taking
brand new scopes off the assembly line and powering them up for the
first time. Believe me, a Variac is the only way to go with a unit
which could have any number of problems at first. Over the years I
powered up literally thousands of scopes this way and never a problem
with current limiting.
