Well ok I'm new here and new to Tig welding. I recently purchased a Dynasty 350, took a Tig course at a Tech. School. Now I am trying to better understand all the settings. The manual doesn't go into very much detail. I am for some reason determined to weld pop cans bottom to bottom. I can do it fairly well but not as well as I would like. In class I was using a Dynasty 300 the weld bead was prettyer than I can achieve with my 350. My bead doesn't look polished like I would like, I'm sure it is just a combination of settings. Any suggestions would be appreciated. And what are tags that you add at the bottom of the post screen?
