Lou, seems that one should be able to take for granted that any iron with an ESD safe rating would have a well grounded tip. However taking it for granted may not be advisable. I have two Weller TC-552 55W irons that have grounded tips yet I can get a volt or two when I read tip voltage to a copper water pipe that my ground bracelets connect to. This makes me want to check the ground in my outlet. I just checked my small Ungar and the lowest reading I can get between it's ground prong and the tip is 3 ohms. Thats the small 25W iron in my photo that I use a lot. Guess as long as I am connecting the tip to my bracelets it's OK. My object when I brought this topic up a week or so ago was to warn others on the group not to take for granted that your iron was safe on modern electronics. I hate to buy a new iron since I must have ten or more around here and running a separate ground from the tip does work. More $ for trains. J
