Question: In arc welding processes like GMAW and FCAW, what does the term 'electrode extension' or 'stickout' refer to?
Answer options:
- The length of the welding gun cable from the feeder.
- The distance from the contact tip to the workpiece. ✅ The length of unmelted wire extending from the contact tip.
- The angle of the welding gun relative to the joint.
Correct answer: The length of unmelted wire extending from the contact tip.
Explanation: Electrode extension, also known as stickout, is the length of the welding wire from the end of the electrical contact tip to the arc. This distance affects amperage, penetration, and arc stability due to resistive heating in the wire.
