When is a stick electrode considered to be 'electrically hot'?

A stick electrode is considered 'electrically hot' when the welder is on because it is energized and capable of conducting electrical current. When the welder is powered on, the electrode is part of the electrical circuit that allows current to flow, which facilitates the welding process. This situation poses a risk of electric shock if someone touches the electrode, particularly if they are in contact with a grounded surface.

In contrast, when the welder is turned off, the electrode is not energized, making it safe to handle. Similarly, during a break in welding where the welder remains off, the electrode does not pose an electrical hazard. Immersion in water can also present a safety concern due to the potential for conducting electricity; however, the key factor regarding the state of the electrode being 'electrically hot' is that the welder is actively delivering power. Thus, recognizing when the electrode is energized is crucial for ensuring safety when working with welding equipment.
