Here's some pics of a couple of vertical up welds. They certainly aren't perfect, but not too bad for not having done any vertical up for about a year.

The pic on the left as you can see also has a horizontal weld. The pic in the center has vertical down welds and of course flat welds

Of course you are moving a bit slower with a vertical up weld giving it more time to heat the material. I have some pics of some vertical up welds, but they are on my home computer....I'll try and post them up later.
A vertical up weld is the strongest weld to do.The way you do the weld creates the peno though.When you start you are suppose to weld one side of the joint for a few secs quickly move to the other side then hold for a few secs.Then move up and down like a triangle so you are just above where you started.If you know what i mean.Then you just repeat.So you will be making little triangles.We tested and broke all our welds with a press and vertical up will rip most of the plate away when broken.Hope this helps.

No concavity but some underfill going on here, Getting lazy
Give me 75% argon / 23% Co2 / 2% O2 gas any day over this stuff.
Note the copper slag on the weld, the steel was clean of any scale before welding, that crap is from the wire alone !!!!

Maybe I should try that.

I weld with the piece clamped in the vise. (Didn't weld the shackle at this angle though).

i have a 1 1/4" thick custom ground welding table at the shop I fab at, it's 6 foor by 10 foot, and i still weld lots of parts in a vise. There's no shame in that, vise's are excellent tools for holding parts stable. Welding at that angle is no probelm either, a good welder can weld any part anywhere any time. I prefer a bit of an angle sometimes, it can be helpful. At home i have a well scorched wooden table (ugh).

Hey Brother....your weld looks good, but it looks like you did not push the insert in all the way....with the bevel built into the insert you should only have about an 1/8 gap....

Just curious...

No, Its pushed all the way in. I beveled the dom tubing and that is actually just the first tig root pass. I put one more pass on it to fill it in. Just did not take a pic.
