I have a microwave oven transformer which i had damaged in the process of removing the high voltage secondary. I will be using this for spot welding 18650 cells. I have all the required figures
I wish to know if change the wire gauge would affect the current output in the secondary. I need the max current output.
As far as I understand the heat loss and resistance depends on the primary winding gauge and the current draw in the secondary depends on the width of the cemetery core and the gauge of the secondary winding, correct ?
With that said 22AWG would be a little less thereby creating more heat in the primary but would help adding more turns on the secondary thereby increasing current draw
