Tig welding aluminum for beginners.

[patriotformula]

Well I got a Lincoln 225 for the garage a couple of months ago and have gotten much better at GTAW steel... well I decided to move on to Aluminum today, and I'm not completely going into it ignorant and have done some research but I cant do it at all.. I have EWP electrodes and rounded the point, cleaned the aluminum with a stainless brush, turned it to AC and about 135 on some 1/8 aluminum. I strike an arc and the aluminum just never seems to melt or do anything very much, I try to add some filler rod to the very small pool there and it just kinda flakes off... Any clue for a stupid beginner? Im open to suggestions!

BTW to all the good aluminum tiggers I have seen over the years cuz it's not real easy!
