What is NOT a requirement for electrode leads in welding?

In the context of welding, especially when using Shielded Metal Arc Welding (SMAW), the requirement for electrode leads centers around their functionality and safety during operation. Electrode leads must be free of defects to ensure there is no interruption in the electrical flow and to minimize the risk of electrical faults that could lead to hazards such as electrocution or equipment failure. They should also be of sufficient length to allow for flexibility and ease of movement around the workpiece while maintaining a safe distance from the welding arc.

The requirement for the leads to withstand maximum rated current is crucial as it ensures that they can handle the electrical load without overheating or failing during the welding process.

Color-coding of electrode leads is not a universal requirement in welding practices. While color coding can aid in identification, particularly in complex setups or when using multiple machines, it is not a mandatory feature for electrode leads and does not impact their primary function or safety standards. Therefore, color-coding is not essential for the performance of the leads itself in the context of SMAW.
