Fronius MW2600 service manual needed

[eddie49]

Translation from Polish:

Greetings,
I have an Oerlikon Prestotig 300 AC/DC. When starting the welder today it showed Error 9. Yesterday it was working OK. Only one LED on the primary side - for 15V - is lit. The voltage on the capacitors is 560 V. The LEDs next to the transistors are off, the inverter on the secondary side is off, all the LEDs on the main board are lit.
Does anyone know where to start looking?

Hello, I'm sorry but I'm writing through a translator. I can buy a damaged Oerlicon Prestotig 300 AC DC, it displays error 6. Does anyone know what this problem is? Regards .

Witam, posiadam Oerlikon Prestotig 300 AC/DC. Podczas dzisiejszego uruchomienia spawarki wystąpił błąd (Err 9). Poprzedniego dnia do końca działało poprawnie. Świeci się tylko jedna dioda (15V) po stronie pierwotnej, a napięcie na kondensatorach wynosi 560 V, diody obok tranzystorów są ciemne, inwerter po stronie wtórnej jest ciemny, świecą się wszystkie diody na płycie głównej. Czy ktoś wie gdzie zacząć szukać

How did you sort out error 6?

The welder is over 23 years old. The "Err 6" error was repaired by the welding machine service. Unfortunately, after a few hours of light welding, Err 9 appeared. There is probably no point in fixing it further.
