What size tungsten are you using? 3/32"
What size filler were you using? .035"
If you have a pulser, use it on the butt welds. I dont know what a pulser is:hand:
Don't try to go further around the tube than is comfortable. Lots of well done starts/stops looks a lot better than long but shaky welds.
