SEC 01 // SYSTEM RECORD
Miller Miller PAPR (Gen 1)
First-generation Miller welding PAPR (used with the T94i-R flip-front and hard-hat headtops). Kept as a SEPARATE system record from the Gen 2 PAPR II because batteries and filters are NOT interchangeable across generations — the single biggest user trap in the Miller ecosystem.
