325EXT Triangular Wave???

[Kempy]

Well I set the AC Balance to 20 and the AC Hz to 40 and i just was able to weld 1/4 aluminum plate. The reason I want to use the Triangular wave is to weld parts onto a boat upside down and it works well on the thinner parts so far. Using the E3 tungsten helps also better then 2% lanthanated it keeps a stable arc and not ball up as much on the end and has a nice clean round ball on the end of the point.

This is where I'd use the advanced pulse.
