A transformer requires a changing input to generate an output.
The three main reasons for the widespread use of transformer are power outage, more power supply and sustainability among consumers. This is what has made the transformers to be much appreciated.
We will describe Justin Foley in Thirteen Reasons Why, [Betrayal and selfish]
The reason for conducting transormer turns ratio is to determine if the transformer is a step-up or step-down.AnswerTo determine the turns ratio if the turns ratio is unknown.
Most outdoor power and distribution transformers are oil filled. There are two reasons for this: (1) to cool the transformer and, (2) insulate the windings and other components, allowing the overall physical size of the transformer to be reduced and, therefore, provide a smaller 'footprint'.
You need two windings because that is the purpose of the transformer - to convert one voltage into another. If there were only one winding, it would be an inductor, or a special case called an autotransformer, but that is still "sort of" two windings.AnswerThe major advantage of a two-winding transformer (a 'mutual transformer') over a single-winding transformer (an 'autotransformer') is that a two-winding transformer provides electrical isolation between the secondary and primary circuits. This is very important for safety reasons and there are many circumstances in which the use of an autotransformer is not permitted.
F.A.U turned off Bad transformer Blown low voltage fuse
To describe vividly. to teachers its very important.

two reasons i can think of: 1 - Probably dont need to, usually welding material of constant thickness. 2 - The transformer is mechanically adjusted on most welders, this means that that there would be a possibility for electricity jumping in the transformer, and premature failure, or fire.
One reason could be a severe fault resulting into huge fault current and thus huge radial and axial forces on the winding and core.
