Talking about winding, what does the 21:4 mean .Observe corect winding polarity?, surely there is no way of knowing on a salvaged trans which end of the winding is which + or -.

Well thats easy to do when you take apart the ferrite core , the hardest part i think is to avoid wire varnish scratch .Surely it's easy to just record whether it went clockwise or anti-clockwise, and wind the new winding the same way?
The only HF transformers I have ever seen outright fail were in high powered SMPS for welders and plasma cutters and even thein the primary fail issue were only in those that they used cheap aluminum or copper clad aluminum for the windings and it simply got so hot it melted itself down at the connections.
Miller Inverter welders to be exact. I used to work for a local welding supply chain store I ordered the replacement parts for the Miller inverter welders by the case.
I'd be surprised to see an ally wound trans in a miller.
Hey tcm
Long time no see. How the oilfields/fracking stuff going?
We have MAJOR resistance to fracking here in our Karoo area. People are VERY wary.

We cant do it fast enough or find enough people to do it here! We need two more Electronics techs as of now. Starting pay is around $80 - $100k a year.
Our last guy came all the way from Cameroon and is super to work with and I love his French African accent too!
I would think that by South African standards $80K - $100K American would make cutting that bum finger off not that big of a deal.
Heck if I could get a job in South Africa that paid a $1 million American equivalent and I had to do the workload I do now I would probably cut the damn finger off myself with a dull kitchen knife.
