Can the pulse feature be used on AC tig process, and is it effective? This is on a dynasty200 DX
Pulse on AC is good for getting a nice consistent lap weld, especially on 1/8" and thinner aluminum. Keeps the heat input lower and the arc nice and focused. I usually run 300 pps, 33% background, 33% peak time and 225 HZ. Welds very nicely.
