The amount of current (amps) is controlled by the user. It's done with a variable resistor. Another thing to note is whether you are welding constant current or constant voltage. If you are welding constant current, the voltage will vary and a set Amp measure will remain constant. With constant voltage, the current will vary and that's determined by the resistance. Constant voltage should be an easier set up. I'm not 100% sure but most stick welding is constant current, which is why increasing the arc length produces more heat, because more arc length should increase the resistance, which would cause the welding machine to increase voltage to keep the current constant.

How is current controlled in welding transformer?
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.

How does a welding transformer work?
A welding transformer uses the alternating current supplied to the welding shop at a high voltage to produce the low voltage welding power
How welding current is generated?
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 alternators the welding current is produced on the?
In alternators, the welding current is produced on the stator winding due to the electromagnetic induction process. When the rotor, which is a magnet, rotates within the stator, it creates a varying magnetic field that induces an alternating current (AC) in the stator windings. This induced current can then be used for welding applications by converting it to the appropriate form and intensity required for the welding process.

What is polarity in welding?
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.
WHAT IS A welding current of E6013?
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.
