so ino this has prob been asked a million times
but i have burned out about my 6th welder in a couple of years. so i want to build a heavy duty mig set to max out about 160-200amp
i have bought a old external wire feed thats 42v ac to strip the feed motor out of.
i have the parts coming to build a 500amp rectifier.
now comes the transformer. i am looking at building a multi tap transformer.
but i was thinking why not use a scr input voltage controller or something simple to control the input voltage.
would make it a lot easyer to build and to repair. any ideas.
thanks
