mig welder stopped working

[rudzis2]

Hello! Merry Christmas all!!!
My mig welder stopped working. A week ago i did a mistake by connecting it to 380v but setting as 220v, when i preset button to weld, fuses in the house were blown away, not in welder self. It is dual machine with 220/380volts. Changed fuses in the house and welder seemed OK, was happy that its working. Then a week later i was working on project, everything was fine, then suddenly it just stopped, the fan was still on but no spark, no wire feed no sound from welder except a working fan.
I dont know if it is related to my terrible mistake a week earlier, but if someone could give some advice on what to look for and what to check i would be happy. I have opened it to have some look and taken a pictures if that helps.
Im no expert, just an enthusiast.
Regards Martins.

start checking fuses first with a meter or battery and a bulb just because a fuse looks OK doesn't mean it is OK
one fuse showing on second pic or board may be more

Thanks for reply, i checked fuse and it is Ok

Check if you have voltage on output of the control transformer. Might also be worth checking the diodes as they can be sceptical to over voltage.

Worth checking if the device that the brown wire is connected to is maybe a trip and may have a reset button that has popped out. Press to reset. It looks like there is no contactor, is that correct?
What make and model is this machine?
Take care as with the power selector switch just dangling it could short.

Here is forum i found in Russian goggle, the guy has the same problem and he said that it was transformer that was bad. The machine is exactly like mine, just names are different, hes is called Spark mine Unistar 200d, they are Chinese.
I tried to check transformer, it has 5 pins, to are incoming 220v or 380v depends on supply i choose, lower 3 ones is out coming i suppose, im getting no readings on either of them. Does it means that transformer is bad? Many thanks so far.
Pop out button is in the place. Im not sure i understand what contactor means sir.
I uploaded pictures with multimeter readings.

Confirm you have input to the transformer and if you don't have an output then it's broken.

 

[rudzis2]

Yes there is an input, but nothings coming out. Will post back when i will get replacement transformer.

 

[rudzis2]

Yes it was transformer on board. Thanks for help everyone.
