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?
