Which type of wire feeder is commonly used when welding with soft, small-diameter electrodes?

• A. Pull-type wire feeder
• B. Push-type wire feeder
• C. Hand-feed only
• D. Rotary-feed unit

Answer: (A)

Soft, small-diameter electrodes are very prone to bending and buckling if pushed, so smooth, reliable feeding matters. A pull-type wire feeder pulls the wire from the spool through the liner toward the gun, keeping constant tension and avoiding the buckling that can occur when pushing soft wire. This setup provides more consistent feed for thin wires, reducing jams and arc disturbances. Push-type feeders can press the wire forward and encourage kinking with flexible wires, while hand-feeding is impractical for routine welding, and rotary-feed units are used for more specialized or high-volume applications.
