The iron the OP has I'm sure it's the same as I posted It's a very well made but like the OP has found out it gets to dam hot to fast.
I've used a lot of irons in the last 40 years there all been usable some better then the rest but still usable big stuff big iron.
But the one were talking about is able to over heat way to fast and make the tip hard to clean. But like any thing if you learn your tools they become usable.
I slapped a dimmer on mine and its ten times better then any I've used over the years I think they under rated it it's hotter then a 40 watt I use on grounds. And it can handle the same jobs easy.
I first got mine just because it was on sale for half price and had a nice case for my tool box on the truck. It solder two 12 gauge wires like butter till it sat in the holder then you had to clean it with tip cleaner. I pull out a work box and a outlet and dimmer from my part box and made a cheap controller for it after a hour and two kinds of solder I tamed her down. It's better then a weller at work that cost over $400 and I have $24 in it.
