You almost don't need an owner's manual it is such a simple machine with so few settings, and virtually no moving parts except the cooling fan and some switches. You could use the owner's manual from any number of other similar machines. I believe they were all made by the same company (Century?) and white labeled for Sears, Montgomery Ward, and others. 6011, 6013, and 7014 are the customary rods to use on any AC welder. You can also run certain DC rods on AC and you an also find an AC flavor of 7018 rods (7018AC) but to be honest, I hate those. They never run real well in my experience.

I like 7014 rods for learning. Jump to 7:43 in this video and you can see that 7014 will practically weld itself
