Tig welder for a beginner

I bought a TIG some years ago (a Miller autoset) and use it frequently but as stated, TIG takes some serious practice and understanding to do well, that said it isn't magic and assuming you are of reasonable intelligence (must be because you are here) you can definitely learn to do it. However, I will say that welding aluminum is a whole different animal and has a lot of issues that welding steel doesn't. Not all aluminum can be welded or welded well, getting it clean can be hit and miss, getting the puddle to form can be a challenge, etc.

I will say this in reference to power; I learned from experience that more power is definitely better and this is especially true when welding aluminum of any real thickness. The first MIG I ever bought was a HF unit and while it did work, I didn't know how must better a good welder was until I bought a Miller 110v Autoset unit. I also eventually bought a Miller 212 220V machine for welding heavy stuff and it works well for that. I once had a big Miller stick welder that was converted to do TIG but it was just too confusing although it did have a lot of power but it was HUGE.
