In what condition should welding and cutting equipment be maintained?

Welding and cutting equipment should always be completely insulated and flexible to ensure safety and optimal performance during operations. This condition helps to prevent electrical shocks and allows for the safe handling of the equipment. Insulation is crucial for protecting operators from electrical hazards, while flexibility enables workers to maneuver the equipment more easily and safely during operation.

Proper maintenance also ensures that the equipment is in good working order, thus reducing the risk of accidents and malfunctions that could lead to injuries. The focus on insulation and flexibility reflects industry best practices, emphasizing the importance of safety and preparedness in environments where welding and cutting activities are performed.

The other options do not provide adequate measures for maintaining welding and cutting equipment safely. Relying on infrequent inspections, only repairing equipment when it is broken, or using add-ons without adhering to safety standards can compromise operator safety and the effectiveness of the equipment itself.
