Hi,
I dismantled this welder, an inverter type rated at maximum 120A @55V, I noticed there's no filtering capacitor at the output. Opened another one and again there's no capacitor. It's all working good though, my work there was just to clean it from dust.
So, what kind of SMPS is this that doesn't need filtering capacitors?
