Could be. I did buy it from a flea market so who knows what happened to that welder before I opened it. In regards of complexity I believe the 164 and the 171 are both two switch forward converters so the differences are minor and dependent on the iteration cycle of Telwin. In regards of complexity the SAF in my other video is more complex. It's is embedded and it has a rare IGBT driver and IGBT brick. Too bad I left home just before making a video of the LINCOLN. That is really complex. Two parallel power boards, 2/3 phase AC rectifying, embedded of course and a lot of sensing circuitry.
Saluti George am un aparat de sudura nu are tensiune pe partea de joasa ce ar putea fi
Prietene,aia nu e placa de Tecnica 171,este de la un Tecnica 144-164.. E mai complexă placa de Tecnica 171.
