In welding circuits, the resistance of the arc converts electricity into light and heat, which melts the base metals. After taking this class, users will have a foundational understanding of ...

FPN: Connecting welder secondary circuits to grounded objects can create parallel paths and can cause objectionable current over equipment grounding conductors. Finally, there is some recognition of ...

When calculating branch circuit loads, what's the maximum load you’re allowed? The limit is this: The total calculated load on a given branch circuits can't exceed the rating of that circuit [220.18].
