Red Seal Welding Practice Exam

What should your electrode stickout be in CAC-A?

1. 2-3"

2. 4-6"

3. 7-9"

4. 10-12"

The correct answer is: 4-6"

Typically, the recommended electrode stickout for CAC-A (consumable-electrode-active-gas welding) is 4-6 inches. This allows for proper gas coverage and prevents excess distortion of the weld. Options A, C, and D have longer stickouts, which can lead to issues such as porosity and overheating of the electrode. Additionally, shorter stickouts may result in inadequate gas coverage and create similar issues. Therefore, it is important to maintain the recommended stickout range for optimal weld quality.
