AWS Welding Inspection and Testing Certification Practice Test

What should not be done when an electrode holder or welding gun is not in use?

1. It should be placed on a non-conductive surface

2. It should be secured in a toolbox

3. It should be placed in contact with a grounded metal surface

4. It should be covered with a cloth

The correct answer is: It should be placed in contact with a grounded metal surface

When an electrode holder or welding gun is not in use, it is crucial for safety reasons to avoid placing it in contact with a grounded metal surface. This action poses a significant risk because the holder can inadvertently complete an electrical circuit if it comes into contact with a grounded surface, leading to accidental shock or injury. Ensuring that welding equipment is not in contact with any grounded metal surface helps maintain a safe working environment and prevents potential electrical hazards. Utilizing proper storage protocols, such as placing the holder on a non-conductive surface, securing it in a toolbox, or covering it with a cloth, all contribute to effective safety measures. Each of these practices minimizes the risk of accidental contact and helps protect both the equipment and personnel from harm.
