Aluminum paramater settings

[cdale2002]

Here is a basic starting point that you can try for 1/8 to 1/8 fillet weld using pulse which I used to welded in the pic below as labeled. I also included a sketch of a good type of point to sharpen your tungsten to (I'd recommend using either 1.5% lanthanated or 2% ceriated). What happens is the small plateu will round over, but will give a good amount of arc starting and allows you to more precisely pin point the arc (I tried the same setup we use on the millers at our shop using 1/8 Zirconium with a completely round tip and the PM256 didn't really like starting the arc along with limited control of the arc). I also used a #7 cup with a 3/32 ceriated tungsten and about 180 amps. Hope this helps.
