Aluminum Tig is not as hard as everyone thinks. If you can pre heat the material it makes it easier. I use a propane torch to do this and acetone with a rag to wipe all it all down as I heat it. As you weld and the material gets uniformly hotter the welding gets easier.

Best to separate all your aluminum tig stuff from the steel. If using all same it will contaminate the welds and make it a lot harder on you.
