For desoldering you can use Weller Dsx-80, this iron has 80W and can be used with the WSP80 profile.
With luck you can find the replacement iron without handle cheap. I designed an grip which can be 3d printed. As vacuum pump I used an old Mercedes door locking pump.
Its a good and cheap solution as you say But the problem is that i already have WXDP120 . In first coarse wxdp 120 iron heating test (witch lighter and two multimeters) i reached Resistance and Temperature values equal to PT1000 probe table values in range 30 to 300 degrees of celsius (ofc with little deviation). Which profile will be best to remake to WXDP120? Also rest of aboved profile will need to be changed :c How to beat that?
Hello Unisolder friends Im very happy user of Unisolder station since last week I solder 10 pcs of it with Weller WD1 and WSP80 (horrible but not impossible). Recently i tested it with Pace TD100, Weller WSP80 and JBC245 irons. I would like to connect it to Weller WXDP 120 (same like ppsati in post #359, directly to iron and sensor of course) and make desoldering station. Could You help me with my problem? I want to ask also great sparkybg, maybe would You write some FAQ for begginers (like me) how to create own iron profile, wchich will describe where in code (iron.c?) and how use PIC software to change iron.c parameters, how found parameters to paste (for example touch to another iron/i mean soldering station like weller/ witch set temperature for a while and read value on unisolder?), compile it all and send it via usb to Unisolder 5.2? I try to understand iron.c, but i see only a equation with constans (parameters) that i dont understand.
PS. Sorry for my English and for my stuppid questions wchich may be very easy for many of you.
