Assembly Instructions 1. Tighten approximately 2-1/2 turns past hand tight. 2. Welding procedure: Use electric weldrod AWS-E7018. Recommended procedure specifies using lower amperage than usual and puddling of molten metal to permit gasses created by lead in steel to work through molten lead deposit. Label Set: FS-2000 (adhesive).
