AG Mechanics CDE Practice Exam

The "60" in E6013 represents what according to the Numerical Coding for Electrodes?

1. 60% duty cycle

2. 60 seconds

3. Tensile Strength in thousands of pounds per square inch

4. Thickness of the electrode

The correct answer is: 60% duty cycle

The correct answer is A. In the Numerical Coding for Electrodes, such as the E6013, the first two digits (60 in this case) represent the tensile strength of the electrode in thousands of pounds per square inch. The tensile strength is an important factor to consider when selecting an electrode for a welding job, as it indicates the maximum load the electrode can withstand before breaking. The other options are not relevant when it comes to the numerical coding for electrodes.
