The items listed are torches only. You still need a regulator, gas and a few adapters to use it with a stick machine. 90 amps is not enough for anything over about 1/16" aluminum. And unless your box has high frequency capability you won't have much success anyway.
The last time I welded 1/4" aluminum with my TIG it burned my face right through the helmet lens. Current was around 350 amps. I was inside the structure being welded so it also burned the back of my neck from reflection off the surfaces.
