Picked up some more scrap. Not sure what coating is on here but I didn't like it.
I tried #6 cup, 120-125amps I believe, still on the same stuff as before. (No changes to equip rest of the pics)
Penetration on the back side wasn't that good, still having issues starting the weld with this type of joint.
Same as previous, just closer:
Backside of previous pic:
Underside of previous.(This is good right, I mean the penetration)
Got a bit more comfortable, starting it and getting the puddle to move is tough still.
