Second, the Miller tech articles mention that since the leg will melt faster, the filler rod should be targetting that puddle more so. Third, I switched to 3/32" rod (I hate to say this, but thanks Craig ).
    And I hate to say this, you're welcome.

    I guess a fourth thing that helped was remembering to actively modulate the pedal when things looked like they were about to get to hot/cold. Still going to take a while to get this down without having to think about the need to do it.
    I spent a lifetime learning that the more steady I could keep my foot on my vehicle's gas pedal, the better gas mileage I'd get. Running the TIG pedal up-n-down like a newly wed has been really hard for me to learn.

    OBTW: Be very carful of heat build-up in your work piece. You'll be wondering why everything has turned to doo-doo. It's real easy to get so focused on your welding that the piece will overheat. You'll start blowing holes or having disastrous droop-outs. And DON'T quench alum. Just walk away until you can touch it again.
