Tip size options?

I'm looking for some help on tip selection for cutting 3/16" and thinner. As far as I can tell, 1.0 is the smallest for the S75 and I want to be able to run lower amps and slower speeds with 16ga-3/16" on a 2x2 table. Do I have other options?

I'm considering a machine torch and thought maybe the S45 would be a better option for the smaller tip range. I never work with anything over 1/4" and usually half that. I like to stay below 40a due to input power limitations too (machine is 60S).
