  • Millermatic 350 will not turn on.

    Bought a Millermatic 350" w/o pulse " powered up fine during testing at sellers get it back to my shop and get it hooked back up and flip the switch and no power. I did have to open the side cover when I got it to the shop and change it over to 230v. I do have power going to the transformer in the back of the machine. Any help would be greatly appreciated.

    Are you sure that the unit has been properly RE-Linked for your voltage??

    Here is a video.. to doublecheck..

    and that it is correctly wired for the proper phase?? NO RED wire connected for single phase..

    Proper manual can be downloaded here if you plug in your serial number.. here

            Maybe this one has no CB1...

            have you cycled the power switch on the right hand side bottom corner of the front panel...??

                I figured it out. Where there machine was set up for 440 volts I had to pull the cover and take the red wire loose from the contactor switch and hook the white wire where the red wire was . Flipped the switch and now I have power. Still need to pull the contactor switch off and clean it since its humming to me. Thanks for all your help.

                  The humming is only a problem if you dont like the tune.
