Ok, so I finally got a welder, a nice older Dialarc 250, which should work for my needs.

BUT! it's set up for 460v. Reading the handy online manuals, I see that it's easy to swap over, but here's my question:

Pictures in the manual show two "horseshoe" connectors or plates, to be placed over the appropriate poles. For 460v, there is only one showing-- on the machine, it is two small pieces, back to back. When switching to 220v, do I need to get another set of two plates? Or is it supposed to be one over each pole??? I don't want to cook anything other than the big box of 6011 rod I got with the welder.

I'll try to call Miller tomorrow but if anyone knows, I'm all ears. Thanks in advance!
