I found an old piece of 4130 that I used as practice material a while back and decided to lay a small bead next to it for comparison.........the bead on the left used a dynasty 200dx with footpedal...it was set to about 60 amps but I was probably only using half, and the two on the right were with the powertig I had it set to 40 amp.....just comparing the difference in how shiny they are...both used 70s-6 rod and red tungsten.
Also is if you look at the two tungstens (1/16) I did a very small bead then removed the tungsten and it had those haz/scorch marks on them (single bead after grinding).....is that normal for them to form that quickly and where they are?
