Transformer question.

Hi All

I have beeb busy with a welder smps, 150 amps.

However, I need to make the transformer and have a E71/33/32 transformer who do well.

I am thinging between round wire or flat wire, I can get copper foil, can I use this also for the primairy, and has this some advances.

I think it is easyer to wind, I have special insolation tape for it.

Further it is meant to use as a co2 wire welder, so I need constant voltage, I have found a program in a cpu and schematic, maybe this is the best way for the feedback.

smps will be so 3.5 Kw.

People who seek transformers for smps, here you can order them, good company, diy friendly...
