In welding terminology, what does the term 'stickout' directly refer to?

The term 'stickout' refers specifically to the distance from the contact tip of the welding gun to the workpiece. This measurement plays a crucial role in the welding process, as it can affect the arc stability and the heat input. A proper stickout distance is essential for achieving optimal weld quality; too short can lead to unstable arcs, while too long can cause an increase in resistance and poor penetration.

In advanced gas metal arc welding (GMAW), managing the stickout helps welders maintain control over the welding parameters, ensuring a consistent and effective application of the filler material. Understanding this concept allows welders to adjust their techniques based on the metal thickness and type, promoting better weld characteristics such as strength and appearance.
