OK quick update. So I found a crack in the neck of my torch so I replaced it.

The Tungsten is no more than a 1/8 to 1/4 Max depending on the size of the cup. I've been using a gas lens but found as soon as I go to a bigger cup the arc goes nuts, I'm not sure why. Seems that regardless of a lens or not. Any cup above a 7 gets a little crazy as far as control. Ideally a 6 works for me but I'm not sure why. I've been adjusting the Argon until I don't see the arc "blowing" around. I just ordered a small gauge to test the flow to the torch as well.

I try to keep the torch as close as possible tilted about 15 degrees. I try to move about 1/8 forward per second, slight move back for the dip. I try to stay a distance where I have a "cone" arc on the material. I've noticed that if too far I can see the arc change and hear the difference when the gas starts to lose the shielding effect.

Oddly enough, I picked up a piece of aluminum again to give it a shot and this is what I got. The skill is in there somewhere lol.

I just can figure out why I keep cooking the steel.

Your gas lens setup looks like a chinese kit to me. Don't expect a lot of good out of them if that is the case. Buy the best consumables availabe—CK and Weldcraft are two of the best. You will never overspend a single penny buying those.
