  1.  @CGT80  for it to be true they'd have had to do some really stupid stuff designing the machine. Basically hobbling it's overall performance. So it's more likely just a misprint. Either way mistakes were made. I've never seen anyone run a welder all the way cranked up anyways so it doesn't really matter. They're just ballpark numbers. When I was little I bought a Radio Shack Dictionary of Electronics and taught myself all of the symbols. That's most of what reading a schematic is. Electricity is one of those things that's always fascinated me. It's right up there with fire!

  2. You weren't sunburnt. You were arc burnt. Arc burning is a lot worse than sun burning.

  3. Come back with that new welder in 50 years and see which one is better then. The old welder will still be working. The new one? Maybe not.

  4. Aluminum is usually welded with AC. So to get your machine to weld aluminum you'd need to bypass the rectifier. There's more to it than that but that'd be the first step.

  5.  @CGT80  why would DC output be higher than AC? You must have magical rectifiers in your welder.

  6.  @CGT80  You rectify AC and you lose something in the translation. That's due to rectifiers not being superconductors but rather semiconductors. So some power is going to be dissipated in heat. In this world you don't get nothing for nothing. You certainly don't get out more than you put in. AC you bypass the rectifiers. You're directly connected then. So you don't suffer from any rectification losses.

  7. If you want to know what's really going on do a web search for pole pig schematic. Then you'll see where your 240V/120V comes from. The secondary load side of the transformer is center tapped. The outsides are your two hots and the center tap is your ground neutral. It's single phase though.

  8. 3 phase is not such a common thing for small shops to have. Most use a phase converter to get it.

  9.  @SchioAlves  it is 240 VAC today but yes. The welder here is 3 phase though.

  10.  @SchioAlves  this video is about that welder so it is pertinent. Then a single phase 240V outlet still wouldn't have helped.

  11.  @SchioAlves  if my reading and comprehension skills were any better they'd be off the chart. Because they're at the top of the chart now.

  12. That's what you say now. But when your new fangled welder breaks down you may sing a different tune then. Remember the old welder is old and it's still working. There's no chance that new welder will still be working 50 years from now. The control electronics in it just are not that long lived.
