MM200 Input Voltage Taps

[jeepgif]

Hello,
I just picked up a MM200 and want to set up the input voltage for 230V.
However the Owners Manual says: Compare the position of the jumper links on the input terminal board to the voltage link arrangement shown on the voltage input label.
I have no label. I think it fell off.

Anyone have a picture of the label?
Or, know the correct taps for 230V?

Thanks,

jeepgif: Is it possible that you have a 230V model, and don't need to be concerned?

Just a thought why there may be no label.

ok, then why the two taps and jumper?

Have you tried to use this place.

The red arrow is the volt select.
It looks like it is set to 230 volt

I do have a copy of the PDF. That is where I got the instructions I referred to in my first post.
How did you conclude that mine was set up for 230v from the circuit diagram number SB-119 327-A? I do not see a connector identifier called out.

Welcome to the forum.

I'm guessing you have a 1981 model MM200. Serial # should start with JB.

You probably have a 200/230v or 230/460v input. Look on the face plate. If you have a 230/460v input, you really can't go wrong connecting it to a 230v source. You'll know when you have the jumper set to 460v. The fan will barely turn on when you power it up.

Jumper settings are in the center of the very first pic. Kind of red color and three brass screws and nuts.

Jumper settings:

200/230v input:
200v = jumper left and middle
230v = jumper middle and right

230/460v input:
230v = jumper left and middle
460v = jumper middle and right

It is common for the paper label in power input to fall off.

PM me your address and I'll email you a manual.

Yes, mine is rated for 200/230 input voltage as marked on the front.
So I should be all set as is. (230v = jumper middle and right)

Edit: SER # HK343965
Found the settings in the "older" model Manual.

Gif,

Your settings are correct. Let me know how it welds. Those old MM200 welders had industrial feeder size feed motors. Very heavy duty.

Your welder must be one of the very first MM200 made. 1979 model.

-i thought my 1981 millermatic 200 was the only one around in mint condition.
your machine looks every bit as good as mine
