Kevin, thanks! I think I'm getting close. I noticed the lack of penetration, too. I think it is because I was doing a butt weld, instead of a lap weld and I intentionally reduced my trigger time. The butt weld, for me, is the most challenging. I tend to burn through, especially if the gap is bigger than right next to each other. That's why you can see in the pics that the two pieces are exactly next to each other.... I am trying to challenge myself and not take an easy way out. Thanks for the feedback! I'll keep trying!
