So I run a Miller Big 40G on my rig. I'm getting some reels setup and would like an easy way to switch polarity. I have seen some Big 40s and TB500's with a large handle on the lower left front panel to change polarity. Cant find it in Miller's literature so cant find a part #. Was hoping somone would be able to point me in the right direction or better yet tell me they had a used one for sale.
here is a pic I found online.
