Great product !! It can turn red a screwdriver in 30 seconds !! Power supply must deliver more than 10 amperes to get best results ;-)

That's amazing Peter.
I can see it being very useful for many a thing.
Something else on my wish list!

I have just ordered one of those. It will be extremely useful for hardening and tempering home-made silver steel cutting tools.
The silver steel bar or plate is shaped by machining/grinding as requires - such as a form tool to finish-turn a finial or a special clock wheel fly cutter. The finished item is then heated to cherry red and quenched in water or oil which makes the steel very hard but brittle. It is then tempered by heating it again to a straw colour (for average hardness) and then allowed to cool in air. The result is a tool that can be used in a lathe etc. to cut mild steel and alloys.

Any idea what Frequency it runs at?
I think I'd better have one for the same reason as Brian.

It's the same technique used to flash getters.

I'm thinking along the same lines as Brian.

I've ordered one.
It should be good for small Silver Soldering and Brazing obs - think Tool Tips.

Also for heating stubborn small nuts that have been glued with sealer or Locktite.

Perhaps to re-getter soft CRT's ?

Interesting! And cheap.

One of the reviews says it will heat only iron and steel - not copper. Wondering why.

Thanks for the feedback - a good fivers worth then!
