dculkins has it right...
Head off to the Vo-Tech for some hands-on and practice, w/a little classroom tossed in for grins.
Didn't hurt to go over the basics and such.
I've been silver-soldering electrical connections for over 30 years - done some Oxy-acetylene (not too pretty) and cad-welding (Really FUN when there's moisture in the area (NOT!!!))
Tried a Mig one time (At least I thought it was Mig...) many years back...seemed to me to be a rich-kid's toy.
But, each method has it place in the the madness.
Choose yours and your path is picked out for you.
Enjoy the sparks!
