| A: Besides the advantages described above, the auto-darkening helmets can remarkably improve the welding quality through liberating your two hands because they are headworn rather than handed. In addition, the auto-darkening helmets become dark in the moment arc flash occurs, as a result, welders can clearly see the welding spot, which improves the welding quality greatly and meanwhile protects welders from eye damage. We believe the auto-darkening helmets are sure to be the labour protection necessities in the future welding industry. |
