<DIV><FONT face=Arial size=2>Ma </FONT><FONT face=Arial size=2>tu niekto
schemu PWM s casovacom 555 alebo 556 ? Najlepsie by bolo aj so spatnou
vazbou...Moze bit aj PIC. Mam iba zapojenie s cmos 4011, ale ta sa mi
nepaci, rozsah ot sa neda nastavit moc dobre.Skusal som aj zmenit frekvenciu,
no stale to ide spolahlivo len v rozsahu cca 30%.Potrebujem riadit posuv drotu
na zvaracke CO2 /stieracovy motorcek SKODA 120...12V/3A/</FONT></DIV>
