A good chance to make your wife a widow, and your children have no father.

When you use a variac you have no line isolation, and if any thing goes wrong
you can be killed quite quickly.
If the neutral wire to the variac breaks, the entire transformer element goes
to line potentional, and it hurts, ask me how I know.......

If you insist on a variac, then put a isolations transformer in front of it.
