I dunno why it took me this many years to learn this but USE MORE FLUX. Seriously. Use so much flux.
Whoa what are they soldering? Barn walls?
It’s likely for stained glass windows.
Huh interesting - thanks
Been there, did that. With a similar iron, I unsoldered am MC68000 CPU (DIL64) from a mainboard. Neither ruining the chip nor the board was an option.
The big tip might be advantageous to desoldering a 64 Pin chip with through hole mounting.
Add lots of soldier wire and a big tip might alow you to apply heat equally so you can pull the chip out.
Still not an easy task, but easier than some tiny microsoldering tip.
I solved it by using cannulas. They are made from stainless steel, and solder won't touch it. They were thin enough to separate the pin from the through-hole. It still was nerve-wracking. That was my main machine I was working on, a nearly prototype Amiga 1000 that had cost me a fortune.
