Hi,
I have found from time to time I need to remove the tip and use a brass wire brush on the tip AND the part of the soldering tool that mates with it. The oxidation (may look like 'mere' discoloration) reduces heat transfer from the 'fire' to the tip.
I hope this helps.

I have had the same experience with three Weller soldering units. Sometimes one gets hot enough then not so much. It could be the tip which can be changed although I haven’t tried that since sometimes it works. If I use two irons it works fine so it acts like there is not enough thermal mass in the iron or not enough heat flow.
