    Pretty darn old program in there, likely a programming glitch, best to take it into a repair shop and get them to down load the new program into it. I can tell simply looking at the front display. You might try a clear all, but turning the machine off, press the mode button, turn the machine on, and with the right dial go over to clr all. release the mode button, and the unit will clear the memory

      Thank you, I'm guessing you found that in your tech manuel???

      I'll give it a try, it worked for my Powermig 300 if you remember.

          Well,
          I did the clear all, and it just returned to err-33, than began scrolling.

          Check on my thread on WW>

          You might be the last resort.
          Everyone tells me its a DOA POS.

            well, its sensing a voltage error, so might want to verify that the input voltage is correct and ok, ok. The big thing in these units is the digital power board. left side of the machine. Make sure that there is 2 red lights on it when the power is turned on.

            Just because your not using the red wire does not mean its wired correct in the machine

              Ok,
              Sorry I haven't been paying attention to this thread.
              If you had been watching the WW thread, you might of noticed I updated the thread a week ago, saying that the machine had blown up.
              Made a big boom, and went dead.
              But I just blew my 50amp breaker, and didn't know it.

              So,
              I Flipped the breaker back on, and the machine powered on, and we are at the EXACT same spot when we started this thread.

              SO,
              I called the Lincoln tech back up, and told him the latest on it.
              He said pull the cover off, and grab a multimeter.
              245vac ac went into the input rectifier, I checked wires 207, and 209, coming out of the input rectifier, going to the board, and we only had 50vdc.
              Kevin said we should have 350vdc going to the board.

              So,
              Cruizer,
              $400 input rectifier replace, or do you suppose it damaged the board when it blew???

              Thanks,
              ~John
