You don't say why you need schematics. Most of the stuff that you need to know to install, use, and understand the welder is covered in the operator manual. You can get one at this web page.
There is also a copy of the schematic diagram on the inside cover of most Miller welders. Please be careful if you're not familiar with high current power supplies, you could get hurt pretty badly in the blink of an eye.
