Internal Replacement Welding Mask Lens for 710G/718G models (MAS PRZ2010)

The Internal Replacement Welding Mask Lens for 710G/718G models (MAS PRZ2010) is a compatible internal protective element designed for use inside the viewing assembly of 710G and 718G series welding helmets. It restores the internal shield layer that helps maintain clear vision and basic protection within the helmet's lens housing, intended for repair or routine maintenance of compatible welding masks.

Advantages

This replacement internal lens is manufactured to match the fit and dimensions typical of 710G and 718G series viewing assemblies, enabling straightforward installation without altering the helmet shell. The component helps re-establish the intended internal barrier against spatter and debris that can accumulate between outer and inner lenses, contributing to longer service life of the viewing system. Using a dedicated internal element avoids improvised fixes and supports correct alignment with external lenses and auto-darkening units.

Suitable for

• Repairing or maintaining 710G and 718G series welding helmets
• Replacing scratched or clouded internal protective lenses
• Workshops and service technicians performing helmet refurbishment
• Home users restoring helmet internal viewing components

Key specifications

• Type: Internal protective lens element for welding helmet viewing assemblies
• Compatibility: Designed for 710G and 718G series helmet viewing housings
• Function: Protects inner area of lens stack from spatter, dust and minor impacts
• Form factor: Flat replacement insert sized to fit standard internal mount points of compatible helmets

How to use

To replace the internal lens, remove the helmet's outer cover and, if present, the auto-darkening cartridge following the helmet manufacturer's safe removal procedure. Carefully extract the damaged or worn internal element from the viewing assembly and insert the replacement lens ensuring correct orientation and seating in the internal mount points. Reassemble external components and verify that the lens stack aligns properly and that the auto-darkening unit (if fitted) operates without obstruction. Perform a visual check for gaps and secure fit before returning the helmet to service.

Usage recommendations

Use only as a direct replacement for compatible helmet models. Inspect the new lens for scratches or contamination before installation. Replace internal and outer protective elements as needed to maintain clear visibility and to reduce the risk of spatter penetration. Follow all safety instructions from the helmet manufacturer and ensure the helmet's overall protective function is intact after maintenance.
