What type of electrodes are pull type feeders typically used with?

• A. Soft wires
• B. Hard wires
• C. Copper wires
• D. Aluminum wires

Answer: (A)

Understanding which wires benefit from pull-type feeders comes down to wire stiffness. Pull-type feeders draw the filler wire from the spool toward the gun, maintaining steady tension and avoiding the buckling that can happen when a flexible wire is pushed through the liner. Soft wires tend to kink or buckle if pushed, so pulling them through with a pull-type feeder keeps the path straight and feeds smoothly, which is why this type of feeder is typically used with soft wires. Hard wires are stiffer and feed reliably when pushed, so a push-type approach is more common for them.
