Variac
Can anyone think of a use for a variac? I've "inherited" one with some stuff I brought its brand new and rs list them at £399,
before I go to he trouble of testing it I'm curious if anyone can think of a use for it

I ued to use one at work, very useful for product testing and repair of switch mode PSU's
* Most variacs are variable transformers that can generate up to and beyond mains voltage.
* Some variacs can be followed by an isolating transformer which allows you to safely work on switch mode PSU's
Some people use them for running foreign voltages and stick a bolt thru the adjustment knob.

Useful for foam wire cutting. As long as you keep the volts too low. Otherwise the wire melts and you get electrocuted. Still if used with caution
very handy.

I have one it can be used for all sorts of things, but variable AC voltage is it's main use. Slowing motors, dimming lights, creating 110v
etc,...

Used a lot by valve amp repair people for bringing voltages up slowly, useful for diagnostics.
DO NOT PUT ON KNOB OR BOLLOCKS!

£399! 
I've got two in the garage that I've had for years. Hmmm I feel an ebay moment coming on.
Tell them about the bent treacle edges!

I used to use one for testing that new products would work at the full range of European mains voltage: 200V - 264.V
If you have old euro 220V devices, you can use a variac to drop our 240V a bit.
You could use one to adjust the temperature of a soldering iron (or anything else that gets hot) or for dimming some types of light bulb.

Bingo
I have one that is pretty old mainly use it for playing around with my amps and little projects. I'm just being greedy and fancy another one
