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.
The E6013 welding electrode is designed for general-purpose welding and typically operates with a recommended welding current range of approximately 70 to 150 amperes, depending on the material thickness and position. This type of electrode is suitable for both AC and DC current, with a preference for DC positive polarity. It produces a stable arc and a smooth bead, making it ideal for welding mild steel in various applications. Always refer to the manufacturer's guidelines for specific current settings based on your welding conditions.
The difference between E6013 and 6013 primarily lies in the designation system used. E6013 is an electrode classification that indicates the type of welding rod, where "E" stands for electrode, "60" signifies a minimum tensile strength of 60,000 psi, and "1" denotes that it can be used in all positions. In contrast, 6013 refers specifically to the filler metal without the electrode classification prefix, but it typically conveys the same properties when discussing welding rods. Essentially, E6013 and 6013 refer to the same type of welding electrode.
AWS E6013 is a type of welding electrode specified by the American Welding Society (AWS) for use in shielded metal arc welding (SMAW). It is designed for welding mild steel and is known for its versatility, ease of use, and ability to produce a smooth, clean weld. The "E" in E6013 indicates that it is an electrode, while the "6013" designates its tensile strength and welding position capabilities. This electrode can be used in various positions, making it a popular choice for many welding applications.
-- negative polarity -- positive polarity
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
Reversing polarity ,changes the rotation of the device you are changing polarity on.
