  • syncrowave 180 doesn't turn on

    Hello everyone, recently bought a miller syncrowave 180 for my little shop and was working fine when i bought it but when i brought it back home it doesnt turn on
    I have opened up the machine and have confirmed it is getting 220 power to and after the switchbut am a little lost what to look for now. The circuit board doesnt have any visible damage either.

    Seems like I'm getting power to the core but there isn't any power coming out of it?

      180's haven't been around for a while. I'll need a serial#. Very unlikely that problem has anything to do with the board, unkown why you would jump to that conclusion.

        I'm away from home for the week so can't get serial but i do have the build date, it was built in 2003 if that helps?

          Sorry doesn't help s that date is likely wrong as well

            Seriall no LC645306

            Not sure why the build date would be wrong? My manual is listed 2004

              Yep, so it was born at the factory on October 10th, 2003.

              Zero error codes, I know you didn't check the input and output of the on off switch, unless your in Europe where 220 exists


              The serial shows me that there was a change midway in 2003, so without it I and you would be hooped on the correct diagram.

                By checking the switch and "seeing" 220 I checked both live wires and got 120 off of each. Inputs and outputs so yes I did check.

                  120???? So phase to phase is either going to be 208 or 230 ish. Where are you getting 120?

                  NO WHERE ARE YOU GOING TO READ 220 VAC

                    Checking the two input live wires with my multimeter yields about 120 each so 240 volts combined. At my outputs on my switch it's jumped and I can read 240 there?

                    Sorry mistyped 220 should have been 240.

                      Not nessessarily, you have to measure the 2 hots, NEVER, the hot to ground, cause that is silly. You could have the 2 120 readings on the same phase. And the machine doesn't run on 120. And so what if you get 2 120 readings, again the 2 hots WILL NOT READ 240 EVER


                      You have a meter, why wouldn't you just read the 2 hot leads, seems really simple

                        But the output on the switch is actually reading 240?

                        But yes I'll double check the reading from hot to hot to make sure it's not running on 110.

                          Just cause you have 2 120's that does not equal 240 when the 2 hots are metered, an example here, is that I'm running 208 3 phase here in my shop, it averages 212 Vac, my plug ins are 120Vac. Kinda see what I'm getting at.

                          So if you metered 120 on the same line, it will zero out on both hots.

                            Yeah i think i understand what your saying. So if i measure both hots and i get 0 than that means im only receiving 120? And if i get like you said 230 or whatever from measure the two hots than i don't have a power problem?

                              Correct. See that machine had an update mid 2003, and has a host of error codes, and because your display is getting zero power, or only slight power, I'm going to guess that its an input power issue.
