Variac is a short abbreviation for "variable autotransformer".  A variac
is
a transformer wound on a circular core and features an adjustable wiper
arm
with a carbon brush.  It allows you to continually vary the output
potential.  Most common variacs feature a hand wheel to adjust the
output,
but the more advanced units are stacked in multiples to control large
amounts of AC power and feature a small drive motor to slowly turn the
wiper arm.  This allows slow and smooth adjustment of the output
potential.
