You may have an instrument (fast blow) type of fuse in your 
variac.  Use a normal speed blow fuse, 10 Amp, and it should work 
fine.  The fast blow style usually blows on the rapid turn on 
magnetism current for the variac core which peaks rapidly above the 
fuses rating.  Or, you have a variac problem.  Try it with no load to 
see what happens.
