Are there add on rectifiers that can be bought to turn an AC welder into a DC one?
Is it that simple, or is there a catch?

is it possible that you might have mistyped what you were trying to say. I cannot think of a reason that diodes would not work well in the output side of a welder other than they might not be able to handle the current. On the input side I can think of a lot of reasons why they would not work starting with you cannot get transformer action with dc current.Rohan when I was 16 I got a job i n the machine shop of a small manufacturing plant. we mostly wire welded but when a Die block in the stamping room broke we had to stick them. This company was started in the 50's and had 4 old giant stick welders. One was a huge refrigerater sized General Electric welder that was AC. It did good bt didnt have neough penetration. an old timer in the plate shop part had some DC rectifiers he tried putting on the out put side but that was trouble some. They worked flawlessly on the input side. Used the DC contered power in the transformer. I welded alot with that welder. I Talked to friend that works there now and he said its used weekly. There also been a few posted in Farmshow magazine. You can go to Farmshow.com and look up back issues but you have pay for a reprint. I think this is the rectifier method they used.
