Here are pictures of my first Tig beads with filler rod
I am looking for input to make me better. Please let me know what you see both bad and good (if there is good it was by accident at this point)
Everlast 250 EX
1.5 Lanth electrode
er70s-2 3/ 32 filler 125 amps on 4T setting
Mild steel 1/8 plate.
Thanks
Ray

what size filler rod?
added to post it is 3/32.
It looks like your starting out pretty good, then the bead gets narrow, maybe this is where you are starting the down slope try making the down slope less and staying with the same width bead by slowing down and or stopping at the end.Picture #4 looks pretty good the width is about the same through out the bead, you just got a little curvy on your path. Keep practicing and have fun with it.:D
Looks like you are off to a fine start. Try to turn yourself into a machine. Meaning remain consistent with everything. Every movement you make with your torch, shows in your weld. It is hard to stay consistent all the time though.
Again, looks like you are doing fine. You are only going to get better and better.
Also know that if you take a break for a while (weeks at a time), when you come back, you are going to have to freshen up all over again.
My feedback would be:
1. work on getting a consistent bead with, by not progressing the torch forward until the puddle has grown to your bead width "target". Keep the same width "target" throughout the weld for uniform weld bead width. You don't have to constantly stare at your puddle to do this, you can use your peripheral vision to see it as well.
2. similarly use the height of the bead to judge when you've added enough filler rod and try to keep that consistent as well.
3. work on running your beads in a straight line. Most weld joints are going to be in straight lines, or at least careful control over the path. I would practice running your beads parallel to one of the cut edges. Which brings up another point, make your cut edges straighter to give you a better reference while welding.
4. to reduce oxidation of your weld joint, try using bigger coupons to conduct the heat away more quickly. Or, try running smaller weld beads (switching to a smaller filler rod if necessary) for the size coupon you are using.
When you feel like you've gotten your fill of running beads on flat stock, next step is to join two pieces together in a butt weld configuration.
