So I got my hands on a Chinese welding inverter. The product and design is by the Chinese company Hanzo, which sells it as the Hanzo MIG 200-D3. My piece is rebranded as Polish Powermat 220T.
The Chinese manufacturer designed the inverter as 180A, the Chinese dealer marked it as 200A, and the Polish one made it 220A
The welder works, but it has no power, my type is the capacitors at the inverter input, they lost capacity and their ESR increased. We'll see when I take it out and measure it,
I have a few questions for now. Please note, I consider this more of a toy than something to repair.
1. Have you found a wiring diagram for this inverter anywhere?
2. According to the first inspection, it is a "classic" connection with 4x IGBT 60n60fd1 ,The current is measured at the shunts 180A 75mV. I found several similar connections on the internet..
I was surprised that there is no LC filter at the output. Is this normal? I would expect that even a small LC filter would significantly improve the quality of the resulting DC current and thus the quality of the window, or am I wrong and even those expensive inverters don't have LC filters?
