So I'm looking to buy a new iron, and I'm looking at Weller, of course, and I see a Weller WLC100 with a wattage of 5W - 40W. Okay. But they make another Weller WLC200 that is advertised as "80 Watts Stained Glass Station" yet is rated at 5W - 40W. Both have a high temp range of 900° F. Coopertools Specs: WLC200 WLC100 And here's the 80W iron that heats to 900° F - just like the 40W iron does. So besides the size of the tips, what difference is there between 40W and 80W? And just to make it more confusing, here's a 60W that heats up to 800° F, depending on the tip you use.
