• To control the welding speed

What is the purpose of using a fan during welding?

• To cool down the weld

• To remove smoke from the breathing zone

• To increase the amperage

• To improve electrode manipulation

Is it necessary to clean mill scale before welding?

• Yes, it is best practice

• No, it doesn't affect the weld quality

• It depends on the type of electrode used

• It depends on the welding position

Why is practicing restarts important in welding?

• To improve welding speed

• To avoid arc strikes outside the weld zone

• To create a smoother weld bead

• To reduce the amperage required

What is the recommended rod angle for stacking a second bead?

• Pointing towards the bottom member

• Pointing away from the base metal

What is the key factor in maintaining a tight arc during welding?

• Electrode manipulation

• Rod angle

• Arc length

• Welding speed

What is the recommended practice for cleaning mill scale on groove welds and bend tests?

• Clean the mill scale for better weld quality

• Leave the mill scale for training purposes
