Which feature is NOT typical of automatic welding equipment?

In the context of automatic welding equipment, the need for continuous observation is not a typical characteristic. Automatic welding systems are designed to operate with minimal human intervention once properly set up. This automation includes the ability to start and stop the welding arc automatically, manage pre-programmed welding parameters, and generally allow only for occasional adjustments rather than constant monitoring. The automation is intended to improve efficiency, consistency, and safety by reducing the necessity for a constant operator presence during the welding process. This allows operators to focus on overseeing multiple processes or performing other tasks, rather than being required to observe the welding operation continuously.
