First of all I'm not a professional welder but have done some TIG /tool steel welding back in my Tool & Die, Mouldmaker days. Have run a Lincoln 225 AC forever in my home shop with good results using 6013 & 7014. Recently came across an old Forney 180 welder with the plug in leads. Has anyone run 7018 DC reverse polarity rods on a welder like this? I know it's still an AC welder but would the leads being reversed allow me to run this rod? Also know there's a 7018 AC rod available but I have a source for the DC rods. TIA.
