I have 3 different Weller solder irons (station type, pencil type, and
butane type). I'm trying to find different size/shape tips for each.
So far, I haven't been too successful.
I've tried Jameco, Allied Electronics, and a few other places.
They don't seem too concerned about tips, just irons.
I'm not even seeing my SP 40 pencil iron, maybe it's no longer
produced. I don't know if the SP 35 or SP 25 tips will work.

Any information, or a nudge in the right direction would be
greatly appreciated.
