question for welders

update report,

Thanks for all the tips, I appreciate the ideas. In addition to better cleaning the biggest improvement was gas pressure. I had the pressure too high and then tried raising it even more.

Finally I realized the excessive gas flow was moving the flame kernel. It was worse in a corner were the gas had no place to escape. The Tungsten "flame" was moving around unpredictably.

As I lowered the gas flow, the weld control improved. I will continue to back off the gas pressure to find a sweet stop. Just finished a good looking weld at 20 pounds showing on the gauge.

With the MIG a clean tip and clean nozzle made a big improvement. The tip had melted to the point of causing the wire to feed slower than normal.

Simple fixes but sometimes a fellow can't see the weld for the slag [or something like that]
