Welding Arc Blow Quiz

What can be done to change the flow of welding current and affect the way magnetic fields are created?

• Shorten the arc length

• Change the angle of the electrode

• Increase the weld current

• Change the position of the workpiece lead clamp

How can arc blow be reduced when practical?

• Tack-weld the workpieces together at the ends and in the middle

• Shorten the arc length

• Change the position of the workpiece lead clamp

• Increase the weld current

What is the normal electrode angle in the direction of travel?

• 15 degrees

• 10 degrees

• 5 degrees

• 20 degrees

What is the recommended length of the arc from the workpiece to the electrode?

• Three times the diameter of the electrode

• Equal to the diameter of the electrode

• Half the diameter of the electrode

• Twice the diameter of the electrode

What can compensate for arc blow by changing the angle of the electrode?

• Changing the position of the workpiece lead clamp

• Keeping the electrode angle at 10 degrees

• Raising the electrode angle toward 90 degrees

• Lowering the electrode angle

What is the effect of increasing the weld current on the arc?
