Which feature of ERW electrode holders facilitates electrode removal?

• A. Ejector mechanism
• B. Water cooling nozzle
• C. Built-in fuse
• D. Integrated cooling fan

Answer: (A)

The ejector mechanism is built into ERW electrode holders to push the electrode out after welding, making removal quick and easy. When you trigger the ejector, a rod or spring-loaded push expels the electrode shank from the holder, so you can grab a fresh electrode or replace the tip without wrestling with a hot, stuck component. This greatly reduces downtime and helps avoid damage to the electrode or holder from forceful extraction. The other features—cooling nozzles or fans for heat management and a fuse for electrical protection—don’t assist with removing the electrode, so they don’t serve this specific purpose.
