K-FRAME STITCH WELDING......THOUGHTS?

I used a Lincoln SP155 220 volt, 0.030" wire and 75/25 Argone/co2. I also used Mapp Gas torch to pre heat any thicker steel so it had excellent penetration. All added steel was 11 Gauge. Easy to bend with heat. All bends were done with a bench vice and a crescent wrench and Mapp Gas as heat. Totally backyard.
