Hi
I've got a Weller WTCP-S iron which needs new tips. I'm probably going to buy a Weller PU-81 (I found one second-hand with the iron as well) since it is temperature controllable.
On my current tips it seems to say "PT-something" (it's hard to read), so I guess I should buy the PT type? There are ET, PT, RT, MT LT... Why do they make this so complicated

I also need a hot air station (I have been doing a LOT of desoldering with iron and wick... so yea it is time), I found something called Toolcraft ZD-8908 which is affordable, or a second-hand one called Atten ST-862D. The Weller ones are pretty much all over $1000.
My questions:1- How to know which Weller tip fit which Weller iron?
2- Is the iron dependent/different for each Weller power unit? F.ex. the PU-81 and WTCP clearly have different plugs - do their iron fit different tips then?
3- any feedback on the hot air stations?
Thank you!
Simon
PS: Just rewatched Dave's series about soldering equipment (here:
)
I also realized this video series is now 11 years old, so when Dave says "oh it's like $100" I thought "great!"... Ha ha yea prices have changed
