I'm cleaning every thing with laquer thinner. (has acetone in it. Leaves no residue.)
I may have to much leading angle. The effect looked like arc blow. Hot gas would slightly melt and oxidize the filler and also allow arc wander towards the filler.
THE BEST TIP ON THIS THREAD WAS TO "SNEAK THE FILLER INTO THE VERY EDGE OF THE PUDDLE.
Kudos to who ever posted it.Last edited by coronan; 04-11-2013, 10:20 AM.

Try to shorten the arc by holding the tung closer to the puddle; suspect you are melting/balling the rod before it hits the puddle, as others have said. Keep the tip close to the puddle and back up a bit (but don't pull away), as you dip the rod to the puddle. By keeping a shorter arc the heat is more confined to the area, so hopefully, the rod will hit the puddle before melting.
Suggest you watch some of the videos at http://www.weldingtipsandtricks.com/ to see how a pro does it.Last edited by Goodhand; 04-14-2013, 10:25 PM.

I like this for cleaning alum not to harsh. I mixed up some in a gal bucket and dropped a spool of alum mig wire that was real old in it for a couple of minutes rinsed it of blew it out and let it dry welded like it was brand new I don't know why it wouldn't clean your filler rod a gal will last you a long time and it beats wire brushing or sanding. I buy it at a local cleaning supply.

I bumped up to a 3/4 " cup and I think it solved all of my Woes.
Acording to the miller Tig Calculator I should use 1/2 to 3/4 cup on 1/4" butt welds.
I had 5/8 cup but couldnt run a bead larger than a pea with out contamination.
When in doubt go up a cup size.
