Something that helped me remember is the + and - thing. Positive + (more)
means more penetration. - (less) Negative means less penetration. Second
thing ......... Straight Stinger Negative ........ I think of SSN (social
security number) ........... Straight Stinger Negative to keep the confusion
of +, -, straight, and reverse straight in my mind. DCSP (DC Straight
Polarity) = Straight Stinger Negative, and the REVERSE (DC Reverse Polarity)
is the other one (positive).
In a positive electrode, the arc goes away + from you, digging into the
metal. In a negative electrode, the arc comes toward - you, melting the
rod. In thick stuff, you want to melt the thick stuff. On thin stuff, you
want the rod to melt.
The thicker (think +) the material, the more likely you will use stinger
The thinner (think -) the material, the more likely to use a negative -
This is only a general rule, and not absolute. But it helped me to get the
jumble of "polarity" straightened out in MY mind until it became more
familiar to me.
