What condition must the electrode lead meet?

The requirement for the electrode lead to be free of defects is critical for ensuring safety and functionality during the welding process. An electrode lead that is free of defects ensures that there is a consistent electrical connection, which is vital for maintaining the arc stability and proper welding performance. Defects, such as fraying, cracks, or other damage, can lead to interruptions in the electrical current, posing safety hazards such as electric shock or equipment failure. Additionally, any defects could compromise the quality of the weld, leading to weak joints or improper fusion, which can affect the overall integrity of the welded structure.

Maintaining the electrode lead in perfect condition is essential for both safety and achieving high-quality welds, making this requirement non-negotiable in welding practices.
