I have an ancient magnetostat Weller TCP, and it still works fine.
I think we can presume that a real Weller will do it properly.
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.
I would NOT assume that the Weller WLC100 does it "the right way", just because Weller also has better irons. It has a dial labeled only in a few numbers.
"Variable power control dial adjusts performance from 5-Watts to 40-Watts for accuracy"In addition, although the base is grounded, the soldering pencil that comes with it is not. Not a good idea with modern MOSFET and CMOS circuitry. Quite a bad idea, in fact.
And I've seen a lot of cheap irons with good reviews. Have you read the Amazon reviews? Often, they received it, it looked shiny, so they left a 5 star review without using it or after only soldering a few joints. And if you've never used a good soldering iron, will you be able to tell?
I've used a lot of crappy irons in my career. Just about every place I've worked, I've been contract labor and had to buy my own equipment. I've come to the conclusion that sometimes you =can= blame your tools, and that cheap tools are expensive in the end.
Hey all, I'm moving ever forward with my project and one thing I'm going to need is a soldering Iron. I've got a soldering gun, but that's obviously not the best tool for the job.
I'm on a stupid tight budget for the time being, so my options are pretty limited....
I'm under the impression I'll need something adjustable for working on things like Arduino Boards. Is this correct?
