Dc welding can be used for non consumable electrodes with consumable electrode heat is transferred from electrode to work by molten metal. Ac welding is desirable for aluminum and magnesium, because it helps break up oxides AC is more stable than Dc.
consumable is when the rod or other metal is also used up in the weld, like common mig welding. Non consumable would be like forms of tig welding that don't use any rods or other metals to join the 2 materials together. This is the Distance
Filler rods are used to add metal to a molten weld pool during the welding process and electrodes actually have electricity running through them to deposit metal into the weld with the exception of TIG welding where the tungsten electrode is used solely for heat.... Hope this was helpful
Think of Polarity as water flow in a pipe. Reverse Polarity means the flow is from the work to the machine. Straight Polarity is flow from the machine to the work. Heat is released when the flow tries to jump the gap. So in Reverse Polarity (where most SMAW is done) the heat builds up in the base metal which is usually thicker than the Electrode. The extra heat there helps melt the base metal. Straight polarity is usually employed when welding thin metals.
Shielded Metal Arc Welding, commonly called Stick welding. A shielded electrode passes a current between itself and the workpiece. Both the base-metal and the electrode are melted by the current and the electrode is consumed and deposited into the melted puddle forming the weldment.

shielded metal arc welding use to electrode metal
Arc crater is the depression in the molten metal created by the end of the welding electrode during the welding of metal.
The 'welding sparks' that come off during welding are metal particles from the filler metal, electrode, or base metal that are lost during welding. The standard term is spatter.
Everybody used to call it "stick welding". MMAW Manual Metal Arc Welding is the correct nomenclature. The "sticks" are electrodes held in an electrode holder connected to a power supply. Establish an arc between the end of the electrode and the metal and move across the joint. As you weld the electrode is consumed. Discard the "stub", insert a new electrode and continue.
The angle of the electrode, the speed of the electrode used to weld and the size of the electrode.
Polarity in welding has to do with the direction of the current in the welding process. With direct current (DC) the welding circuit can either be straight, or reverse polarity. When the machine is set for straight polarity, the current flows from the electrode to the weld surface and creates considerable heat in the metal. When the machine is in reverse polarity, the current is backwards and is flowing from the metal to the electrode causing a grater concentration of heat at the electrode.
Manual Metal Arc Welding(MMAW) Also GTAW (TIG) and GMAW (MIG) The MIG wire carries electric current so it is considered the electrode. TIG the Tungsten is considered an electrode.
It is sometimes called "stick welding", because of the filler metal. The filler metal is in the form of heavy wire coated with flux.
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.
Consumable electrodes actually form the filler metal of a weld. Stick and wire are examples of a consumable electrode. TIG on the other hand only produces the arc for the weld, and the filler metal is fed into it. The tungsten (the electrode) of a TIG torch does not enter the weld.
