Never tig welded before I got my 200t. Not formally trained in any welding.
Went to scrap yard and picked up some stainless to play with. Maybe 16 guage sheet. Cut out 6- 4" squares and went to town practicing outside corners.
Used 1/16 tungsten. Tried 1/16 filler. .030 stainless mig wire. And fusing.
Started out horrible. Then got waaaay better.
