What is a normal Electrode extension for a FCAW-S?

  1. 1/2 - 1 1/2 inches

  2. 1 1/2 - 2 1/2 inches

  3. 2 - 3 inches

  4. 3 - 4 inches

The correct answer is: 1 1/2 - 2 1/2 inches

A normal electrode extension for FCAW-S is typically between 1 1/2 - 2 1/2 inches. This allows for proper electrical contact and control of the welding arc. Options A, C, and D are incorrect because they either have too short or too long of an electrode extension, which can result in poor weld quality and potential electrode sticking. It is important to follow the recommended electrode extension for the specific welding process to achieve optimal results.
