What is electrode extension, otherwise known as "stickout"?

• A. The distance that the end of the welding wire sticks out beyond the contact tip
• B. The length of electrode
• C. The distance from contact tip to ground clamp
• D. The diameter of the electrode

Answer: (A)

Electrode extension, or stickout, is the distance the end of the welding wire extends beyond the contact tip. This small gap in the wire path directly affects how the arc forms and how the weld behaves. If the stickout is too short, the tip can overheat or the wire can burn back into the tip, causing feeding problems and an unstable arc. If the stickout is too long, the electrical resistance in the wire path increases, which can soften the arc, raise the voltage needed to maintain it, and often lead to more spatter and less consistent weld penetration. The right stickout helps maintain a stable arc and good weld quality, and the exact value depends on the wire type, diameter, and welding setup. The other options describe the length of the electrode itself, the distance from the tip to the ground clamp, or the electrode diameter, none of which define stickout.
