So...I am pretty new to TIG. I have been messing around on some small scraps of stainless. This is was a T welded in the flat position. I was tryning to walk the cup along the pieces but im having trouble making the bead look "normal" it seems to have an akward shape to it. Any suggestions?  Also Im trying to move slow and dip my filler faster to tighten up my ripples but im having no luck it just keeps melting back and dropping off the end into or infront of my puddle, when i back off my pedal i dont get the smooth sransition from the bead to the base metal. Is there some "sweet spot" with my pedal that I am missing? Any help or suggestions would be appreciated. Attached Images

Reply:I'm also very new to tig, but I was having the same problem with my filler melting when I was practicing aluminum and holding my torch a little bit more vertical seems to help the problem.Thermal Arc Fabricator 281Miller 350PMiller Syncrowave 200Lincoln ProCut-55Jackson NexGen
Reply:On many internet message forums, you'll be told to use small filler metals....which only adds to this problem.  I most often use 3/32" filler.Proud to be a UNION worker.  Better pay, better benefits, better work environment.  UA Unions = working for the working class!!
Reply:I may not be able to help you as I rarely use a foot pedal with TIG. I just don't like to drag the damn thing around with me all day. I set the welder for the material I am welding and use speed and filler rod to control the puddle. I do use the pedal with irregular fit-ups/joints and when welding thick to thin especially with aluminum.However, your picture is not to clear but looks pretty good. Appears you are not far off from a good quality weld. Actually all I see from the pic. is a little irregular speed and puddle width.Walking the cup on a T joint is straight forward. The only advice I can give is this. Don’t hang out and don’t starve the puddle. Use enough heat to keep it moving.As long as you have the correct filler for the material you are welding it is a matter of practice. I think you will do just fine.Good luck. Stay with it and keep pics. coming.
