Hey,
Welcome to the forum. There are a few Big Aluminium brains on here, so somebody should be along to help you directly.

i find most of my burn thus at the end but i know why that is and im working on fixing it.....death grip+mashed peddle=burn thru.....
Life is not a journey to the grave with the intention of arriving safely in
a pretty and well preserved body, but rather to skid in broadside,
thoroughly used up, totally worn out, and loudly proclaiming
- WOW- What a Ride

On thin stuff, that's my preference... To start in a little way. Then, when I come back to it, I do that bit downhand and taper the heat off a lot to close the last bit.

Which end is melting - start or finish? or both?
I agree with the other guy's suggestions. In addition, don't forget your filler rod! - you can use it to immediately fill the receding edges on startup and add that crucial little bit of metal that you need. When you get near the end and everything is about to go pear shaped (because you forgot to back off the pedal or didn't start your downslope early enough), you can leave the rod in the puddle to absorb some of the heat and make sure your weld doesn't keyhole too much.
