Managed to scrounge up four 250A diodes the other day. Big sumbitches. Is the conversion as simple as a bridge for the conversion? Is it best to have any kind of choke (reactor) or is this something I can whip up as well? For my 180 amp Lincoln, how big of a heat sink would I need for these diodes? I wasn't sure if there was a rule of thumb for diodes not working very hard. I also managed to pick up a couple 125A triacs at Boeing surplus the other day for five bucks a pop. Was wondering how much fun they would be on the input to control the current a little better. Anyone done this?
I used to be an electronics tech many years ago and forgot all the good stuff. Sorta feels embarrassing asking these questions, but welders tend to have issues normally not on common electronics circuits.
