In case of C245 tip you have no power output limits? JBC specification for 2BB station says Output Peak Power 130W / 23.5V. I assume they use 130W only for some short periods (such as warm-up), but don't expect they will put such stress on the tip for long time (while soldering some large joints).

[quote author="neslekkim"]I can use the T210 and T245 on both the 2BB station and the DIT station, same plugs, only the microtweezer that have an sligtly different plug.
So I would guess it should work?[/quote]

Did you use T210 on 2BB station? It seems like "unsupported" configuration according to JBC website (there is special CD-S station compatible with T210 - Output Peak Power 40W / 23.5V). Looks like you can destroy T210 tips on 2BB station because you measured C210 resistance only 0.2ohm.

Maybe is C210 detected on 2BB and lowered or disabled output power?

[quote author="arhi"]...and for JBC I did not find any mircowave tips at all (and if they have them they are probably like Weller paying royalty so again probably not too much choices and high price)...[/quote]

JBC has four Mini Spoon tips: C245067 C245938 C245931 C245965 for drag soldering. Looks like mircowave tips.

[quote author="neslekkim"]I have an Rigol ds2202a-s, i only need to learn how to capture with it, also got an agilent 34461A today but i guess that is not helpfull here.
What and where should I measure?[/quote]

Put Rigol into A-B differential mode (disconnect ground clips from your probes) or use differential probe and measure voltage on heater terminals.

Just for reference I'm attaching example from my HQ-SOLDER/30 (cheap) station. You can see simplest triac regulation without zero-crossing detection (the M channel, ignore 1 and 2 channels). AC half wave @ 50Hz.

It would be interesting to see 2BB output.

[quote author="neslekkim"]I'm not using my 2BB after I upgraded to DIT, so I could take it apart if there is anything interesting to see inside there.[/quote]

[quote author="sparkybg"]As far as I can see, there are 2 power MOSFETs inside, and it seems they have separate gate drivers. That's why I think it is possible that they are using 12 and 24 volts on the tips.[/quote]

neslekkim, any chance you open your 2BB controller a capture T245 heat-up phase with oscilloscope?

sparkybg, thanks for this really nice project and all the effort you are putting into it!
I'm considering building it from the scratch into aluminum box, similar form factor like "esol" Weller driver project on eosystems website (I'm unable to link due to forum anti-spam measures).

I'm thinking about option to drive also JBC microtweezers PA120. According to the JBC website they are managing each cartridge individually. Didn't you think about it?
