      I was concerned about that too, though the Miller Big Blue 251D is
      rated @40V DC 250A at 100% duty cycle per their spec sheet. These
      welders can be used in fab shops etc. around the clock under constant
      use.

      I agree with you that an electrical engineer needs to design the
      system.
