hi there as above wonder is there somewhere I could purchase a 36 volt ac to 120 volt ac transformer.
I am using it to connect an American imported power supply control unit for a push pull wire feed gun to a uk 3 phase welder.
The power supply for the gun requires 120volt ac in and the welder I have had a 36 volt ac output on the back so if I had a transformer in line I could wire it up and the whole setup would be self contained rather than plugging in the welder and supply separately.
If you're in the UK and you have a 400vac (380vac) 3-phase feed. Just connect two of your hot phases (230vac across each) to a 2:1 step down to get your 115vac (USA). Most of your travel shops should have simple, low current transformers for a very low price.
