What is a typical electrical stick-out for FCAW-SS welding?

• A. 3/4"
• B. 1/4"
• C. 1"
• D. 2"

Answer: (A)

A steady stick-out helps control the arc length and ensures good current transfer into stainless steel when using flux-cored welding. For FCAW-SS, about three-quarters of an inch is typical because it provides enough electrode extension to keep the arc stable and the puddle under control, while not being so long that the arc becomes difficult to maintain or that current is wasted through excessive resistance. If the stick-out is too short, the arc can become unstable and the weld may not fuse properly. If it’s too long, arc control suffers, spatter and wandering can increase, and you may fight for a consistent weld. So, three-quarters of an inch is a balanced, commonly used length.
