Quick question for my welders about AC/DC polarity.
So I want to practice before taking a weld test. I have a Lincoln AC-225 stick welder. I want to practice open root vertical open root horizontal and overhead. I wanted to try this with 6010 and 7018 but I only have this AC 225 at the moment. Should I buy a AC/DC 225 welder for practice? Or would I be good with the welder I have now to get some practice in on open root but obviously I would have to use different rods. Anyone mind helping I really just want to get practice in since it’s been a while since I’ve welded I don’t want to lose my touch.
