What extinguishes a welding arc? changing the work angle roughly 10 degrees using a 7018 low -hydrogen electrode on carbon steel using DC current to create a concentrated magnetic field raising the end of the electrode too far above the workpiece

Question

What extinguishes a welding arc? changing the work angle roughly 10 degrees using a 7018 low -hydrogen electrode on carbon steel using DC current to create a concentrated magnetic field raising the end of the electrode too far above the workpiece

Answer 1

Raising the end of the electrode too far above the workpiece extinguishes a welding arc. When the electrode is lifted too far from the workpiece, the electrical circuit is broken, and the arc cannot be maintained.
