you might be able to tig it by pre heating it and using a lower amperage setting. You might be able get it to weld a little better with some preheating. best way to preheat aluminum is make a nice sooty acetylene flame and coat the part with soot, then make a neutral flame with a oxy torch and heat the part until the soot burns off. then the aluminum if preheated just about perfectly.

it is only 3/132 to 1/8 thick ,there should be no reason to preheat. U should see what happens it doesent really pool just pops
