I think we can presume that a real Weller will do it properly.
Good to hear! :) I googled the model and it had good reviews on most places I checked, and they seemed to be legitimate, but then again it is the internet.... It's not always easy to tell who's got real reviews and who's paid to have them written. That's actually one of the main reasons I posted this, I've trusted the wrong reviews a couple times and ended up with junk. But alot of people are surprised that you can find decent items for decent prices if you put some work into it.
Having a threaded ring to hold in the tip was a terrible idea, as the heat/cool cycles while using it cause it to unscrew itself, sometimes literally in minutes. The three little dents used to hold in the bit the collar threads onto, similarly loosens itself from heat/cool cycles.
It takes a long time to get to equilibrium temperature, then drops 100F or more while soldering one connection. Then takes around 10 minutes to get back to equilibrium. I find that if I turn it up enough to stay hot enough to solder, it will heat until the tip burns black when back in the holder. So I had to turn it up to use it, turn it back down to put it back in the holder. And keep pliers handy to keep tightening the collar. And watch out for the entire tip/collar/retaining ring falling out. I'm not exaggerating.
Sounds just like the way my Ebay Iron was built! the tip screws into the end of the collar, and the retaining ring holds the collar to the body (I think I used the right terminology, I honestly know more about names of the parts of a plant or flower than I do about the names of the pieces of a soldering Iron lol.
I showed Momma Saint (my Mom) my new iron and even she could tell the difference, the weller has a bit more weight and a more 'solid feel'... By solid feel, I mean I'm not worried about anything falling into my lap when I'm working! :o Not to mention if that happens I'll have to explain the oddly placed scars to every girlfriend I ever have again lol
After looking at the Tenma and comparing it to the Weller, it seems like they just used the cheapest parts they could find and built a movie prop version of the WLC100. I can't tell for sure, but is the Tenma iron attached to the base permanently? One of the first things I noticed about the WLC is that it's Iron doesn't require the station to work, which I could see coming in handy in certain situations.
