In a standard welding transformer, the size of the iron core is determined by ____.
A) the distance between the coils
B) the length of time it takes for the magnetic field to build up and collapse
C) the desired thickness of the weld bead
D) the speed of the rotor

Question

Quizplus · Accepted Answer

The size of the iron core in a welding transformer is determined by the length of time it takes for the magnetic field to build up and collapse. This is because the core is responsible for transferring the magnetic energy from one coil to another, and the size of the core affects the speed of the magnetic field buildup and collapse. A larger core will allow for a slower buildup and collapse, while a smaller core will result in a faster buildup and collapse.
