Magnetic arc blow definition
WebMagnetic arc blow, also known as arc wander is the arc deflection caused by distortion of the magnetic field produced by an electric arc current. When welding … Web6 aug. 2007 · At low voltages (6-48V) and a given load (W), the relay may be designed with a contact/air gap sufficient enough to break the arc when the contacts open. When the same relay is required to switch greater loads, or when the voltages exceed 48V, ‘magnetic blowouts’ can be added to increase the effective air gap.
