I have an older model soldering workstation. The tip is Cat. № 6402184. Sorry…the Cat. No. 6402184 is from a Radio Shack soldering iron tip replacement page online. If you need any help w/ my current model identification, please let me know.
I am trying to find a threaded insert tip but seem to lack the research skills as of now.
P.S. Does your company carry such a tip for threaded inserts? The tips are 1/4" while the insert to the soldering iron for the tips are the same, i.e. 1/4" OD.
Here is a photo:
That should make it easier than me describing things.
