What is the relationship between the diameter and length of carbon rods used in carbon arc gouging and their corresponding gouging efficiency and groove dimensions?

The diameter of the carbon rod in a carbon arc gouging machine determines the gouging power and the basic size of the groove, while the length affects the continuous operation time. 

These three factors work together through current adaptation, extension length, and gouging parameters to directly define the gouging efficiency and groove specifications. 

The core relationship can be summarized as follows: "The larger the diameter, the higher the gouging efficiency and the wider and deeper the groove; 

the length determines the single-operation endurance, does not directly change the groove size but affects stable output."
