What is the general thought on how to move the Tig torch while welding. Is it a back and forward movement or a circle type movement while moving the puddle. Its been a long time since I have used a Tig torch and forgot how I used to do it. I seem to get great penetration, but weld appearance is not always that great at least to me. If anyone could post some of their welds or practice peices I would appreciate it, so I can see if I'm being to **** on this.
