I can’t seem to get this stuff to weld for anything, no white on the outside of the weld… been everywhere on settings. I had to run a few beads on a practice pipe after trying this just to make sure I could still weld.

What is everyone using to sharpen tungsten?

This one has to handle 100 psi. I think I’m getting too hot on the quick flanges. They dont really penetrate the other side though.

⅛ aluminum 150amps with pedal 17cfh #5cup 3/32 tungsten and filler 150hz 31AC balance 5356 wire

Still can’t wrap my head around tacking. If I tack on the very sides I am fine. But if I tack about a millimeter from the side it just burns through. Settings are 120 amps 120hz 3 seconds post flow. 1/16 blue tungsten 1/8 aluminum. And I realize I went too cold in the second pic
