Hi, this is my first time posting here. I am quite new to the machinery world, so please forgive the dumb questions. I just got a Harig 612 off Craigslist and am starting the process of getting it set up. I was expecting it to be 3 phase, but my novice reading of the motor plate suggests it is single phase that can be wired as 115V or 230V. I have not been able to find any references to single phase Harigs. Am I reading this correctly? Has anyone heard of Harig making single phase 612's? I think that the serial number is 2547 (number on the rim of the table). If this seems abnormal, does it suggest that someone swapped the motor at some point in its life? Last question: How would I find documentation on how to wire it for 230V vs 115V? Thank you very much for your time and sorry again if these questions display too much of my ignorance.

Not sure if they ever did sell those grinders with a single phase motor or not. Clearly it has one on there, so it was either sold that way or someone swapped one on. Run it. Doerr is a good motor, so no worries there.

Wiring diagrams for dual voltage motors will almost always be inside the electrical junction box on the motor, as is noted on the info plate of yours at the lower right.

The junction box doesn't have its cover, which is where I am guessing the diagram was. I'll look at it closer the next couple days and see if the wiring is intuitive. Thank you!

It looks like you will be wanting to wire it for 230 as Bozeman sits pretty high eh?
I'm used to adjusting clutches and jetting for Cooke City or Lincoln, but I've never heard about needing to adjust the voltage on my grinder for such.
