What is Arcing? - Definition from Corrosionpedia

Arcing is an electric current that is brief, strong and highly luminous. An arc is the luminous current discharge which is produced when strong current leaps across the gap between electrodes or within a circuit. Arcs that are created on specially designed electrodes are capable of producing ultra-bright light...

Welding Terms and Definitions Dictionary | Red-D-Arc ...

- In this welding process, an electric arc is created between a coated consumable electrode and the work piece to be welded, causing the parent material to be fused together and the electrode to melt. The electrode is of a similar material to the parent material and by melting both together it provides the weld (or joint) with a reinforcing filler material.

What Is an Arc Fault and What Causes It? - The Spruce

The term arc fault refers to a situation in which loose or corroded wiring connections create an intermittent contact that causes electrical current to spark, or arc, between metal contact points. When you hear a light switch or outlet buzzing or hissing, you are hearing arcing as it happens.

What Is an Arc Fault and What Causes It? - The Spruce

It may be a precursor to a short circuit or ground-fault, but in and of itself, an arc fault may not shut down either a GFCI or a circuit breaker. The normal means of guarding against arc faults is an AFCI (arc-fault circuit interrupter)—either an AFCI outlet or an AFCI circuit breaker. AFCIs are intended to guard against the danger of fire.
