What problem can occur if the welding wire is too straight?

• A. The wire may float through the contact tip causing loss of current pickup
• B. The wire will jam the feeder
• C. The wire will overheat
• D. The wire will corrode rapidly

Answer: (A)

Electrical contact between the welding wire and the contact tip must be maintained to transfer welding current. If the wire is too straight, it can ride through the contact tip instead of staying seated against the tip’s inner surface. When the wire no longer makes proper contact, current pickup is lost, causing an unstable or interrupted arc. The other issues listed—feeder jams, overheating, or rapid corrosion—aren’t directly caused by wire straightness in the same way and are less likely to occur from this condition alone.
