Why should a welding machine never be overloaded?

A welding machine should never be overloaded because doing so can lead to overheating, which can damage internal components and reduce the machine's lifespan. Overloading can also compromise the quality of the weld, resulting in weak joints and potential safety hazards. Additionally, it increases the risk of electrical failures or fires, posing dangers to the operator and the surrounding environment. Therefore, adhering to the machine's specified duty cycle is essential for safe and effective operation.
