Lincoln Electric Viking PAPR (3350 / 3250D FGS / 3350 XG)
Lincoln's welding PAPR built around the Viking 3350 helmet platform (systems K3930-4 standard battery / K3930-6 extended battery). NIOSH 42 CFR 84 approved loose-fitting PAPR, APF 25, three-stage filtration (spark screen KP3936-1 → pre-filter KP3935-1 → HEPA filter KP3424-2). Verified against Lincoln's own publication EE14.747 — which also proves the widely-circulated "KP3934-2" filter number wrong.
