submerging transformers in oil?

I'm building a ark welder and i know they get very hot, iv seen some people in ''the internet'' submerging their transformers in transmission fluid to keep em cool under excessively heavy work loads.My question is what effects does oil have on wire insulation?And what about the transformer varnish and core insulation wads and paper?


Transformers can be submerged in oil like the oil cooled transformers.The transformer varnish, cfore and paper can withstand transformer oil. Just use a clean transformer oil.

Your right to be cautious. There could be water, metal, plastics in transmission fluid. Used or new. It is designed to help cool a transmission among other tasks. They use oils and other things in power transformers up on power poles. I know cause one near me leaked. A junk yard might sell you that fluid. A letter to the varnish and paper maker might give you a clue.

Only impurities will have an effect on insulation. Best if boiled first to remove any condensation, then seal the container.
