I want to be able to cut expanded metal, draw the least current, spend the least and have cuts clean enough to tig weld as cut. I could see cutting 1/2" aluminum and 3/8" copper on rare occassion. I'm leaning toward the Hypertherm 1000. If I'm willing to max out at 1/4" copper and 3/8" aluminum, and I am, then I'm thinking about the Hypertherm
600. BUT, the 600 is not a G3. What is a G3, and is it better than the 'normal/old' 600? Thanks.- posted
