Depends on the surface area and the initial temperature.
You can easily do something about the second one...

Warm it up in the oven first, take it out, then make your solder joint straight away.

20 ga is pretty thin..... a 25 watt iron should have no problem....maybe your tip needs cleaning or a new one

it might be 18. it flowed easy like onto the terminal for this switch, but i couldn't get it to work on this fuse holder.

i just plugged in this transformer for the first time and i didn't die.

Hmm, might be a long shot, but is that a transformer secondary your trying to solder? They are usually covered with some lacquer that’s not always easy so solder. If so try scraping it off with a knife.

ROTFLMAO.

Frustrating, isn't it?

Cheers,
