Spool-on-gun wire feed system is best described as which option?

• A. Pull System
• B. Push System
• C. Push-Pull System
• D. Spool-On-Gun System

Answer: (D)

Spool-on-gun wire feed systems place the wire spool directly on the welding gun, so the wire is fed from a spool mounted at the gun rather than from a separate feeder box. This tight, gun-mounted arrangement makes the system compact and particularly useful for aluminum or small-diameter wires, where a long feed path from a distant feeder can cause feeding problems or birds-nesting. That’s why this option fits best: the defining feature is the spool located on the gun itself. The other terms describe how the wire is driven along the feeder-to-gun path, not where the spool sits. A push, pull, or push-pull setup refers to the drive method, whereas a spool-on-gun system specifies the physical placement of the wire spool.
