There are a lot more settings than that. One drawback to a multi-function digital display is one pic will not show all the settings. Sine-wave is a lot less tolerant than square for dirty material in general. TIG is a lot different than stick and MIG, if you won't eat off it, it ain't clean enough for TIG. Make everything bright and shiny, and wipe it down with a solvent like acetone. Use a stainless brush dedicated to aluminum and carbide burrs instead of grinding discs.

Do you have a clean ground directly to the piece you're welding ?

Looks marginal from the video. You can see the ground clamp, but the material is far from clean and no idea what that coating is. The fact that it does fire the main arc at some points and not others is a little odd.

I see it now But the metal looks rusty.

I tried it again after about a hour to cool and it's working again
the metal is aluminum the stuff you can see is glue it is clean where I'm welding
Maybe it just got to hot ?
