What is the cause of a rough and irregular bottom edge during OFC?

  1. Travel speed too fast

  2. Travel speed too slow

  3. Too high gas pressure

  4. Using a large tip

The correct answer is: Travel speed too slow

During OFC, the cause of a rough and irregular bottom edge is usually due to the travel speed being too slow. If the travel speed is too fast, the bottom edge may become smooth but the overall weld may be too thin or weak. If the gas pressure is too high, it can lead to excessive spatter and an uneven weld. Using a large tip can also result in a rough bottom edge, but it is not the main cause. Therefore, the best option is to adjust the travel speed to ensure a smooth and consistent bottom edge during OFC.
