Lincoln Wire Drive for NA-3SF and NA-4F (142:1) (3/32-7/32) K209A MERV 16 The 50 lb hermetic can

The 50 lb hermetic can format minimizes packaging waste while maintaining hydrogen-control performance for high-volume shop use

A built-in variable moisture vent provides additional control over internal humidity levels

Gas selection: LA-90 performs best with argon-rich shielding gases that minimize heat input and maintain the alloy chemistry in the deposit:

Use on carbon and low alloy steels for good puddle control on roundabout welding
