Hi, I've got an old transformer type 300 amp two phase arc welder that runs on volts,but I'd like to get it to run on 230v,when I took the top of it off I notice it has two primary windings(which seem to be the same size I'll check resistance) which are in series with two phases connected across them,I'm wondering if I get a 32amp fuse put on sw/board with 6mm wire and heavy duty plug and put the two primary windings in parallel would my welder run on 230v,or will that be 30volts to much on each primary and would it cause a problem.
