Cass Nawrocki says that if this issue happens with TIG welding, it can often be overcome by setting the amperage much higher than usual, but cutting the burst time significantly. He believes that in TIG welding, the issue is caused by "cooking" the metal and getting it to boil. Melting the metal should be the goal, not boiling it. He suggested to me a two-step pedal action. The first step is to melt the rod, but then move right on to a burst of pedal to melt the panel, but end this quickly. Cass has done many rosette welds with a TIG.
