Cold heat?

[KenWittlief]

my son got one - it does work

but

the tip has to maintain electrical contact on both sides of the tip for it to heat

and as someone else said, there is voltage present across the tip (I dont know how much)

I like my Weller. Never yet grabbed it by the wrong end and burned myself. And Ive never NEEDED to stick a soldering iron in my pocket 3 seconds after using it.

If you need to cool an iron quickly you simply wipe it with a wet sponge or paper towel.

Neat product, but I thinks its a solution in search of a problem.
