Jim I totally agree thin stuff like this just stitch a little at a time. The Zig Zag i when you are trying to penetrate thicker materials.
My old man is a welder, and it took years before he didn't grind down my welds and redo. The slightest pin hole he would grind and weld. I was getting the knack at it but I still and learning. Infact this year I was welding my snow plow and I couldn't figure out why my welds were sucking so I called the old man and he saw that I had a fan blowing where I was welding. I thought I was being smart by not breathing the smoke, but what I was doing was blowing my shielding gas away.
