Hi N5uzt!
Check out Ed Craig's website: http://www.weldreality.com
This place is a very good repository for GMAW facts, figures, and helpful training information. I highly recommend it!!!
Hobart Institute of Welding Technology has some very good training materials as does Miller Electric, althuogh for some reason or another, I cannot get into their website so, maybe I have a problem with my SSL security encryption or are other people experiencing the same? Lincoln Electric also... Here are their websites:

Look up Miller Electric in Google because I cannot seem to get to their website, sorry!
