    Miller syncrowave 300 woes

    I picked up 3 of these units not too long ago. I planned on keeping one for myself. Anyways I have one unit that is not giving any output voltage... Ive set it up for stick welding and cannot get it to run.

    The unit powers on but makes some sort of buzzer noise (maybe a contactor issue?) for about 3 seconds then the noise stops. the fan comes on and the power light comes on.... anyways I made some videos so someone may recognize the issue!?

    Ok guys got it all figured out preciate ya 7A749...

    the buzzing ended up being the cooling line solenoid but it was not the source of the absent voltage output. That ended up being the PC1 which was loose enough to not make full contact in the terminal. Unit is working flawlessly now. thanks everyone for the help!

    thank you sir, I imagine I would want to put my multimeter on it to make sure its getting 24vdc as well right?

    Take a look in the Resource section on this site for your machine manual and wiring schematics and you will also find the location of those two relays in the parts section of the manual. They should be very close to one another.

    Good luck!

    Well, your vids never worked for me anyways. And since no tech is there to look at it, all we cn do is throw out suggestions. You want it fixed take it to a repair center. Could be a relay, could be a failed contactor. If you have zero electrical knowledge, us suggesting things is is little useless. However if you know someone handy in such things. Have him post here then we can easily figure it out.
    I'll get it figured out I think. I do appreciate your help though buddy.

Im not quite sure what the "coil part" is either... there is a ton of coil parts in this massive welder.

    could that be the reason im not getting any voltage output? also would that explain why its a loud buzz then after about 3 seconds it stops?
