I don't know anything about this but I know electricity. The AC going thru a
transformer would make a higher or lower voltage depending on the winding. An recifier would change the sine wave into DC with straight line pattern. An inverter changes DC to AC. I have one on my house that makes my solar panel output into the AC my house runs on.

Rectifier dc
Good point Kent, a rectifier isn't as flat as a motor generator.

DC on aluminum
I finally got time to fiddle with welding aluminum with the DC machine. Maxstar 200LX. The "LX" has tons of programability for pulse and ramps. I didn't use any of that for this test. It works pretty well on .05" 6061. I was using a 1/8" pure tungsten at `150 amps. More than enough power. On 1/8" thick material the tungsten burned off. My first attempt was with 1/16" filler. It was too much filler. The arc likes to wander more than AC. Need to keep a short arc. Seems to be very sensitive to conductivity. The arc will want to be all on one side of the joint. It took lots of motion to get the arc to go on both sides. While I am figuring this out, I blew a hole. Second try went better. Bottom line, you can weld aluminum with a DC supply.
