Just wondering....have the manufacturers gone to aluminum windings because it's actually a performance improvement over copper, or is this just a cost saving measure? My guess is that copper works better and because of this I'm tempted to buy a used Miller 130XP or Hobart Handler 120 rather than a new Millermatic 135 or Lincoln SP-135 Plus, or am I wrong here?
Thanks,
Bill
