Any sparkies in the group?

Do we have any electricians in the group? I have an issue with a small appliance that I would appreciate some help with.

I brought back from Australia a pyrography pen - just like a soldering iron, only much, much hotter. Similar to this one:

It's rated for Australian power, although it's from the US market. It cost $120 AUD and was a gift, I wouldn't have paid that amount for it. It worked exactly twice, and then died a horrible, melty death.

Initially it seemed to be running too hot, and then went cold on me. I took it apart, put it back together (what we Aussies call "fixing it"), and it fired up again - but too hot as it then started melting the grip.

I can post a photo of the guts if anyone thinks they can constructively advise.

Any thoughts?

Just curious, how is it rated for Australian power if it's US market?

Sounds like it was meant for 110v power and killed itself because of a 220 main.

OK. I'm curious. Show me a pic of the inside thinggie that looks like a diode . Maybe one that acts like a voltage regulator and another that turns on/off when it gets too hot.
Do they have any numbers on them ?

My bad choice of wording - I think it was manufactured in North America somewhere, but for the Australian market. I'll check the power ratings on it later.
