DC Polarity Question
I have been welding for 25 years (not professionally) and 5 years ago upgraded to a AC/DC welder.
I really like to weld with DC and I have great results, but I do not fully understand polarity issues.
What is "reverse polarity"... Stinger (+) or (-)?
What are the advantages to either normal or reverse polarity?
FYI, I have a Miller Thunderbolt XL AC/DC 225 Amp welder.
Thanks in advance for your advice!
