welding rod is used without applying current through it while the other one is, current is passing thru it..i.e. Welding rods are used in TIG welding process while Electrodes (E6011, E6013, E7017..etc..) is used in SMAW process

The new principal inside welding machines is based on metal-arc welding, whereas the older welding machines used electromagnetic winding to increase the current in welding rods.
A transformer is needed in a welding machine to adjust the voltage and current to suitable levels for the welding process. Here’s why: 1. Voltage Reduction: Welding requires a lower voltage than is typically supplied by the mains power. A transformer steps down the high voltage from the power source to a lower voltage that is suitable for welding operations. 2. Current Adjustment: Welding processes often require high current to generate the heat needed for melting and joining materials. A transformer can adjust the current to the necessary level, ensuring proper welding conditions. 3. Safety: By reducing the voltage to safer levels, transformers help prevent electric shocks and ensure safe operation during welding. 4. Controlled Heat Generation: Transformers help control the heat output by adjusting both voltage and current, which is crucial for achieving high-quality welds with proper penetration and bonding. Overall, the transformer ensures that the welding machine operates effectively and safely by providing the correct voltage and current for the welding process.
E6013 is a mild-steel, all position, general-purpose welding electrode (rod).
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.

Regulating the medium of welding according to the needs
A welding transformer uses the alternating current supplied to the welding shop at a high voltage to produce the low voltage welding power
Welding current is typically generated through a power source that converts electrical energy into a suitable form for welding. This can be done through mechanisms like transformers, rectifiers, or inverters, depending on the type of welding process being used. The current is then delivered to the welding arc, where it generates the heat necessary to melt and join the workpieces.
in welding machine, the transformer used is basically a current transforrmer. so by changing the tap of secondary side of transformer, we can increase or decrease the current in the transformer.
