Operation should include

• travel speed
• travel/electrode angle
• arc length
• current setting
• electrode size.

Process/Skill Questions:

• Why is it important to have the correct electrode angle?
• What happens when the travel speed is too fast or too slow?
• What happens when proper arc length is not maintained?
• What is arc blow? How can arc blow be controlled?
• How does the welder know if the amperage is too high or too low?
• What is duty cycle?  Why is it important?
