Glenn, take a look, perhaps you can add it to the other welding video link in the FAQ section.

I get a white screen when I try the site. The computer here at school is pretty slow, so I'll try it again at home.

 

and when you compare the different welders.. take a look at the low end of the ampere range... specially when you have to weld some thin metal.. if your low end ampere is to high you easily burn holes in the metal.
