Why are some carbon arc electrodes copper-coated?

To determine

To state: the reasons why some carbon arc electrodes are copper coated.

Explanation

Copper coating on the carbon electrode is useful to prevent the electrode from overheating. Copper is highly conductive in nature and can dissipate heat faster to the environment.

Copper has high electrical conductivity which allows the electrode to carry higher current. The high magnitude of current generates more heat as well as generates sufficient heat to form a fully fused weld...
