Tig Practice, Feedback wanted

I made some T joints for practice out of some scrapyard steel. It's 1/4 thick if i remember right. I ran the first pass with no weave at 110-120 amps with 1/16 70s-2 then a weave pass at 125-130 amps with 3/32 70s-2. I am not a welder but a pipefitter with tack quals, and I have an Everlast 160sth at home I mess with.
Just looking for some feedback on the welds, I already brushed these but it looked like i moved too slow by the heat line, and the gray color of the weld before brushing.
Any feedback is welcome... Thanks!

You look like you are careful with your filler placement and have a steady hand.
With 1/4" material, and a fillet weld, max your 160 amps out and get going - likely took quite a while at the amps listed.
I would max your 160 amps on 3/16" fillet too.
Looks good
Edit: I know you use much lower amps tacking a beveled pipe, but on fillet welds you get to crank it up.

Sweet, thanks guys.
Now that I think about it, when I ran the first pass I was having to move slow to get the two plates to tie together before adding rod. On the second pass I wanted to be able to move slow and concentrate on keeping the weave tight and my filler addition.
I have some that need the second pass, then a third and fourth that I will try maxing the machine out on.... I'll post those pics when I have the chance to run them.
