Hey Guys Another Newbie Question

First Off I Have A Millermatic 210

I Know That The Thinner Wire .023 Is For Thinner Metals
And The Thicker Wire .030 Is For Thicker Metals
But On The Weld Parameter Chart{in The Owners Manual**
I Could Use Both Sizes But With Different Settings

Is One Size Better For Lets Say 1/4'" {because The Chart Dont Show Anything Above That For The .023 Diameter**
For Penetration Or Strength Or Anything
Thanks For The Help
