Question about Miller welder?

I just purchased a miller big blue 400D diesel dc welder generator . I will be using 7018 rods. There are two controls on this unit, amps and volts, for best welding results, what is the best setting? I understand that metal thickness will change this this, but I' ll be starting on 1/4" plate. Any help will be appreciated.

    When using a welder,use amperage setting .You need to set the machine to the size of rod that you will be using.

    I don't remember, but the best thing to do is test it. Get some stock that's not worth anything, then do some test welds. Every machine is different, even if I knew the settings for a similar machine, that doesn't mean they would be right for you and your machine. I like to weld a little hotter and faster than most people, so I would be at a higher setting than you might like. Some people like to to colder and slower.
