POW. no more power.

[geneb]

I have a VEVOR MIG 200A. It has been a great economical machine.
Today it made a loud POP when I turned it on. Now, no lights, no power. I checked for a reset or fuse. NOTHING. Any Ideas where to start?

Take the cover off, look for black components on the boards, starting with where the mains connects to (obviously, have it unplugged)

Hi and welcome to the Forum.

Inverter welders are not an easy DIY repair, and the circuit diagrams are rarely available. The power semiconductors can be expensive, and new ones may fail again due to the control and driver circuits being damaged.

Thread 'parweld xts162dv repair'

Mar 24, 2024

hi Everyone
I'm new to the forum and thank you in advance for any help I can get. I acquired this Parweld xts162dv and at the moment it's completely dead. No lights or display working on the front panel. I wonder if anyone here has got service manual or diagram for this welder or similar please or any idea where i can buy it. I tried to google it but no joy so far. Any clues would be much appreciated. Thanks

has some general troubleshooting hints.

**Please note that the large input capacitors will hold charge, at up to 325v DC, even after the machine is unplugged.

If you have the correct test equipment and are confident working on live circuits, you could check the 110 or 220 volts AC voltage across the rectifier input, and the 156 or 325v DC output across the rectifier and capacitors.
