I was given a Twentieth Century Arc Welder model # 40 serial # 812476 by my grandmother after my grandfather passed away reciently. I have a question about it. On the front it has 4 holes in which to plug the cables into. I know that it has two different settings a high and a low, my question is I dont know which holes are the positive and which are ground. By looking at it I asume that the left side is the low side and right being the high side, and my guess would be of the holes that it goes positive-negitive-positive-negitive. am I correct in assuming this...Thanks for your help
