all of my tips oxidised so fast
Idk why but all of my tips just oxidised so fast. I mean like 3-4 in 5 hours of working. The end of the top gets dark and stop working.
I use a 110V-240v/90w soldering at 330-290 c heat. And idk why it’s happening to me.
“Now they are 4 tips completely burned out.
I don’t have a brass wool cleaner.
