see the detailed article here http://goo.gl/9wB5Tg and visit the store here http://weldmongerstore.com/ Roy Crumrine aka "crummy_welding" on instagram is building some aluminum iceboxes for corvettes. So its a good example of how to learn from watching someone elses technique... welder settings like ac balance, frequency, and amperage along with arc length, torch angle, speed of travel, addition of filler metal ...all make a difference and these are the things that you need to watch when you are trying to learn to tig weld.
