AC Welder to DC conversion.

Did you actually read any of my post? /forums/images/graemlins/confused.gif /forums/images/graemlins/confused.gif /forums/images/graemlins/confused.gif

It basically said that the 80v number sounded like a Peak to peak value... convert that to rms, which ar ethe numbers we are used to dealing with and that is about 28v .. which is about right...

I've done this on an old Miller Thunderbolt 225 amp. unit.
If anyone is still interested, I will post some pictures.

It works absolutely wonderful. I didn't use a reactor or capacitors.

Okay, I posted five pictures of the rectifier. I did not post a schematic/circuit diagram since it is only a full-wave bridge but if anyone needs the schematic, I will draw one.

Any comments negative or positive will be appreciated.

I think most people were expecting you to post your pictures as attachments within this thread.

Joe posted them in the Photo Gallery - Here is a link to one of them.
