For FCAW-SS welding, a typical electrical stick-out is 3/4", which of the following is true about stick-out length?

Explanation:
Stick-out is the length of wire that extends beyond the contact tip into the arc. For FCAW-SS, about three-quarters of an inch is typical because that length helps keep the arc stable and provides reliable deposition without overloading the gun or starving the arc. If you shorten it to about a half-inch, the arc can become unstable and feeding issues may occur. If you lengthen it to around one inch or more, the arc length increases, driving higher heat input and more spatter, which can weaken control and penetration. So the best statement is that the stick-out is about 3/4 inch.
