Old Weller Soldering Station........

Not open for further replies.


If you have and love like i do my old WTCPT soldering station, then you might have a surprise coming, like I did. I am now unable to find replacement tips! The model is probably over 40 years old!
Help please.
The tip's part# is TPA7. The "7" stands for 700°F, it looks much like the newer tips but the newer tips do not have the number indicating the temperature stamped on the end.

I now have no spare but I am saving the burnt-ut one so I might be able to fit the temperature sensor on its end to a newer tip.

Please comment.

Up-date: Finely found a company that has plenty of tips. But they have a $8.50 S&H for orders under $25.00. So I ordered 10ea, so if you need a PTA7 Weller tip, I can ship you one for $5.00 if you are in the USA
The company is: All-Spec.com
