So here is the little puppy, a made a few photos of the parts, I noticed that it really only misses the Front panel and some small things but not more than that. It can all be fixed easily, so I think for 50 quit I made a good bargain.
I took a look at some of the circuitry and have to say that it is a very very simple and legit design.
The main inverter PCB has what looks like a H- bridge DC-DC converter. The big transformer you can see on the inverter board (I labled the pats in one picutre) is the main transformer. It primary is driven with a few power trannys and the secondary gets rectified with two diodes (so the sec is a normal winding with a center tap being - aka ground).
A second board is used to drive the HF ignition transformer and has a little of torch contol circuit.
There is only one main board that controls everything, most of it is SMD and the main control chip is covered in epoxy, so sadly I can`t tell what chip they have used.
There is also some things the manufacturer did nice. Like that shunt built in to the outut connection or a "quick and easy" amphenol plug adapter
I will clean the good boy up, rebent the back panel and try to get it up and running.
I just have no idea how to start builting that front panel thing.
This is something for the
digital guys here, not really for me. I will measure out the dimmentons and make a custon front panel out of sheet metal with a foil screen in front of it, I will also plan to make a PCB beind the front panel with all the digital stuff.
I would really apprechiate if anyone could give me just a little idea how it all works. Or upload the schematics of the machine if you have one.
I actually put the photos to dropbox because here they will be either to big or jpeg.
