[Moved] help me repair a welding inverter ?

[tadworth]

Anyone familiar with these machines ?

Mine drops the voltage to zero as soon as i close the circuit, amps and OCV read normal with my DMM. i was told it was definatly the capacitors, but these are 3300 uf, way out of my meters capacitance range, they charge from the DMM normally, and there's no obvious burn out to the machine.

If i can locate the problem it will be a great start.

I have a diagram and repair advice sheet from the makers if you need it.

It would help, if you post a wiring diagram and tell exact type and manufacturer of the device
and explanation , how the fault occurs.
