in welding sometimes your electrode got stuck to your work piece so a very high current would flow and no voltage at generator teminals. only a small voltage will produce in the armature due the residual magnetism in the machine itself.
The only type dc machine that can operate satifactorily in this situation is a shunt connected dc genrator.
This type of generator can run and exceed it full load current. if it allows to run beyond its rated load or its loads becomes zero ohms, then this machine is able to take up that load.(short ccit condition)
So in differential generator to make it use for electric arc welding, just simply short out the series winding so there would be no flux induced or produced in it. only the current flows through the shunt winding.This time the generator is now running as a normal shunt connected dc generator. voltage output can be adjusted/varied by means of rheostat connected in series with it and armature.

What is welding generator?
A welding generator is an electricity generator that is commonly used in places where the power needed to arc weld is not readily available. They are usually powered by gas or diesel engines and have a high, stable energy output suitable for powering a welding machine.
What is the difference of efw and erw?
EFW: Electric Fusion Welding is a more general term which includes Electric resistance welding (ERW) and other types of welding such as Arc welding.
How do you turn a 1964 Lincoln welding machine into a big generator?
It's an engine driven generator like a Ranger, correct? They already come set up to be used as either welding machine or generator when they come from the factory.
Can you use home generator to power arc welding machine?
As long as it is rated for wattage output for required voltage for welding machine
What is Welding Speed and Welding time for Co2 Welding Process?
Your question is incomplete. Which process? Which electrode? What is the basemetal, which position? etc etc
Can an electric welding machine be powered by a portable generator?
Yes.
What is full form of ARC in arc welding?
The 'arc' in arc welding is not an acronym but in turn is a reference to the electric arc that is being generated during the welding process.

What is the temperature of arc welding?
Arc welding temperatures can range from 5,000°F to 20,000°F, depending on the specific welding process and materials being used. These high temperatures are generated by an electric arc formed between the welding tool and the workpiece.

What is the importance of a welding ground in ensuring a safe and effective welding process?
A welding ground is important in welding because it helps to complete the electrical circuit, ensuring a safe and effective welding process. Without a proper ground, there is a risk of electric shock, fire, and poor weld quality. The ground also helps to stabilize the electrical current, resulting in better weld penetration and overall welding performance.
