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.
What is a typical open circuit voltage for an arc welding machine?
I read that it can go up to 80 Volts, any more and it becomes a shock hazard to the operator.
Who invented the first welding machine?
Advani company was manufactured the first welding machine
Why thyristor used in resistance welding machine?
For firing current between the the moving arm of the gun and the fixed arm
Which component of a welding machine changes AC current to DC current?
In a welding machine, the rectifier is responsible for converting AC into DC. AC current fluctuates, but DC provides a steady flow, making welding smoother and easier to control. Many welders prefer DC for its stable arc and reduced spatter, which leads to cleaner welds. Some machines even offer both AC and DC options, allowing welders to choose based on the material and type of welding they need to perform.

What is AC welding machine?
An AC welding machine is one that uses electrical power from house or shop and has a controlled output in AC or Alternating Current.
Do I need regular oil changes on an oil cooled welding machine?
no
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 type of welding machine does not have positive and negative terminal connection?
Transformer type welding machine

What is a welding lead?
the welding lead is the cable coming from the welding machine that either feeds the wire and shielding gas (mig) or or provides current to the electrode through the holder

Why do we need a transformer if we use a welding machine?
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.
