Electrons hitting things at high energy is what produces the heat.
Because Ben
Franklin guessed wrong, the electrons flow toward the + terminal (from minus
to plus). So, if the electrode is negative, and the work positive, the
electrons
are flowing into the work, and depositing most of the heat there. That
is straight
polarity, with the heat mostly going into the workpiece.

I find it easier to use AC :-).

I have found that the absolute best way to remember polarity is whatever
works for YOU. And, you have to weld long and often enough to know the
difference. After that, it's just rote.

I like to keep a clear shop ticket holder attached to the side of my Miller
XMT with the settings for Mig, Tig, and SMAW charted for each application.
