Hello,

I am attempting to repair a Cebora Power Rod 1565 welder. This is a
switched mode type device.

One of the power MOSFETS is visabely blown. Where could
I start looking for a supplier of this device. I only
want a one off.

Type W20NB50 made by ST.

It's a common enough type with suitable substitutes also made by most major
power semi vendors.

Maybe if you said which country you live in I could help advise a source.
