You can weld with E6013 using any polarity. Use DC - or AC for thin sheet metal. Use AC if you have arc blow problems.
DC - has the lowest penetration
DC + has the most penetration
AC splits the difference

E6013 is a mild-steel, all position, general-purpose welding electrode (rod).
Knowing the polarity of transformers is important if they are to be connected in parallel.

The E6013 welding electrode is a versatile, all-purpose electrode with a coating that provides smooth arc characteristics and good penetration. It is commonly used for general welding applications on mild steel and is known for producing clean and minimal spatter welds. The E6013 electrode can be used with both AC and DC welding machines.
-- negative polarity -- positive polarity
Reversing polarity ,changes the rotation of the device you are changing polarity on.
Resistors do not have a polarity. BY DEFINITION, a resistor is a device that follows Ohms law, and does so regardless of the polarity in which it is inserted into a circuit. Manufacturers of resistors do all they can to make their resistors follow that definition. One way to make a resistor have no polarity is to build it so that it is mechnically symmetrical about its two leads. Doing so will ensure that it will also be electrically symmetrical, and thus non-polarized
No. Electromagnetic fields have polarity.
Yes in AC circuits the terminology reversed polarity means the hot and neutral are reversed to what they should be. In DC circuits reversed polarity means that the positive and negative terminals are reversed to what they should be.
