Wire speed is significant too and I believe it determines the amount
of energy (heat) applied to the metal.

Hi, Mike.
Trick (if I remember correctly) with MIG is to remember that voltage equates to
penetration. If you are penetrating too much, drop the voltage back and see if
the process is less like the plasma cutter you mentioned earlier.
I _strongly_ recommend a class of some sort. I went to Washtenaw Community
College and took a [6-weekend, I think] course in welding for auto restoration
which was worth much more than I paid. I still need to practice more, but the
class was the best investment I ever made. Period.
HTH,
Donald.

Doug,
For me yes TIG is easier but it is easier for several reasons. First,
I learned to weld with oxy/acet torch and TIG is similar so I am used to
it. I went to MIG and failed miserably on sheet metal, could weld all
day long on thick stuff but sheet metal kept blowing through.
