my mig machine has voltage and amperage adjustment. How do I set these?

I have a Miller Pulstar 450. For Mig I have two adjusting dials, one for voltage and one for amps. How do I set each? What is the significance of each? Most mig machines have only voltage.

--------------------------------------------------

I checked and it seems this is a pulse model...so the voltage knob might be for background voltage and the amperage is the peak amperage on the pulse wave.

I have no experience with this machine so I cant really help much...

anyone else got anything?

Interesting. It does have pulse in two ranges - 60 and 120 pps. So if you are correct, and if I use the machine without the pulse feature, should I crank the voltage up and adjust the amps as needed? Or should I adjust both to correspond by percentage? Also, I have never welded with pulse. Any insight on when I would use those settings would be appreciated.
