Tig welder for a beginner

Just like others have said I think you would be better with a spool. You need to weld steel pretty good before trying aluminum. Also like others have said it must be clean and free of dirt. I used green tungsten on aluminum and red on steel with good results. One thing about aluminum is it is not forgiving with a tig meaning dirt in one spot or the wrong position on the foot pedal and POOF you now have a big hole to fill.
