Are you using a tig or a mig? if tig then 85-90 amps is plenty
for mig 120-135 is more than enough and on 1/8 material there should be no need to make multiple or triple bead passes on that.
I completely forgot that we were talking about .125, even though I had just written it! I disagree though about beveling the material. Even though the bevel will be very slight, it will still improve penetration, and can actually make it easier to lay a nice looking bead. Personally, I would rather leave a pretty bead unground...but I am strange like that. One of these days, I would like to put a rod together with all old school techniques...stick welding, hammer welding, air chisels, and hacksaws...now where to get the baked enamel job, that is the question.
