Those were tacks, I tacked in several places and welded over most of them. You know maybe I did use filler, on the cart the instructions recommended not using filler on the same type of corner weld. In any case trust me I suck at TIG still. I think the reason these practice beads on the stainless came out nice is I had it clamped to a giant aluminum bar. When welding up the welding cart kit man freaking burnt through so many times (CENSORED) lol
My overall point, even a noob hack TIG welding without any training I was able to get the job done on several projects which I attribute to how good the 255ext is and how easy it was to understand, setup and use.
