The wire spool hub should be adjusted to which of the following?

• A. Prevent Unwinding of the Spool
• B. Allow the Wire to be Removed Without Restriction
• C. 25 Psi Minimum Torque
• D. Allow Wire to Fed Freely, Without Backlash When Feeding Is Stopped

Answer: (A)

The key idea is that the spool hub should create a small amount of drag to prevent the spool from turning and unwinding when the feeder stops. By applying this resistance, the wire stays neatly wound and won’t feed out on its own, which helps prevent tangles and inconsistent wire length during pauses. If the hub is too loose, the spool can freely unwind, causing feeding problems; if it’s too tight, starting feeding may become hard or cause resistance to feed. So the best choice is to prevent unwinding of the spool. The other options describe either allowing unrestricted removal, specifying an unrelated torque value, or allowing free feed with no back resistance when feeding stops, which would defeat the purpose.
