The tip will last until the iron coating wears through and the copper
slug physically erodes.
I would suspect that the switch contacts in the handle of your iron have
broken or welded closed.
If viewed in the dark, an "always on" TCP will get red hot.

I use a PTF7 solder tip on my WTCPT and recently found that after about
5 minutes of use, the tip suddenly starts to develop a thick char at the
end and makes the solder turn dark. I replaced the tip with a newer one
(<5 hours of use) and the same thing happens to that one. I will next
try a brand new tip to see if the same thing happens. Either the problem
is with the tip or it is with the heater/barrel nut assembly
contaminating the tip. Has anyone experienced the same thing? How long
should a typical solder tip last? Has anyone found a tip cleaning or
storage method that helps prolong tip life?
Thanks.
