Question: 1 / 400

If the bottom edge of the OFC is irregular and rough, what is the likely cause?

Incorrect gas flow

Travel speed too slow

The likely cause of an irregular and rough bottom edge of the OFC is a travel speed that is too slow. This is because a slow travel speed can cause the weld to cool too quickly, resulting in an uneven and rough surface. Incorrect gas flow (option A) could also contribute to this issue, but it is not the most likely cause. Option C, incorrect tip size, is also not the most likely cause as this would only affect the size and shape of the weld, not its surface. Finally, option D, faulty equipment, could also contribute to an irregular bottom edge, but it is not the most likely cause as a slow travel speed would have a more significant impact on the weld surface. It is important to maintain the correct travel speed to ensure a smooth and evenly welded surface.
