I have a miller aead. I set the weld rpm to 3000. When i start to weld with the rpm drops down to about 2000 to 2400. Any ideas about what the issue could be?

As Mchevelle suggested - perhaps a governor issue.
I've seen weak speed springs allow for excessive governor droop or perhaps the spring is anchored in the wrong governor lever hole affecting its sensitivity. Moving the spring anchor point closer to the governor operating shaft will make it more responsive. Too close and the engine will surge.
